1

A student makes two sticker patterns.

Pattern A rule: start at 4, then add 1 each time. Terms: 4, 5, 6, 7

Pattern B rule: start at 1, then add 3 each time. Terms: 1, 4, 7, 10

The student says the ordered pairs $(A, B)$ are: (4,1), (5,4), (6,7), (7,10).

Which claim about the patterns is incorrect?

The second ordered pair should be (5,4) because 5 and 4 are the second terms.

The third ordered pair should be (6,7) because 6 and 7 are the third terms.

The first ordered pair should be (4,1) because 4 and 1 are the starting values.

The fourth ordered pair should be (10,7) because the last terms are 7 and 10.

Explanation

The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 4 and adding 1 to get 4, 5, 6, 7, and Pattern B starting at 1 and adding 3 to get 1, 4, 7, 10. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (4,1), (5,4), (6,7), and (7,10), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show Pattern B catching up to and surpassing Pattern A due to its faster addition rate. A common misconception is reversing the pair order, like claiming (10,7) for the fourth terms, but it must be (7,10) to match (A,B). Graphs of paired patterns help visualize errors in pairing or ordering. Overall, such graphs reveal growth comparisons, aiding in correcting claims about term positions.

Two patterns are used to plan supplies for art class.

Pattern A rule: start at 2, then add 4 each time. Terms: 2, 6, 10, 14

Pattern B rule: start at 3, then add 2 each time. Terms: 3, 5, 7, 9

A student wrote these ordered pairs $(A, B)$: (2,3), (6,5), (10,7), (14,9).

Which claim about the ordered pairs is incorrect?

The ordered pair (14,9) matches the fourth terms of Pattern A and Pattern B.

The ordered pair (2,3) matches the starting values of Pattern A and Pattern B.

The ordered pair (6,5) matches the second terms of Pattern A and Pattern B.

The ordered pair (7,10) is correct for the third terms because 7 and 10 both appear in the patterns.

Explanation

The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 2 and adding 4 to get 2, 6, 10, 14, and Pattern B starting at 3 and adding 2 to get 3, 5, 7, 9. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (2,3), (6,5), (10,7), and (14,9), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show Pattern A growing faster, with correct ordering essential for accurate representation. A common misconception is reversing pairs like (7,10) for third terms just because numbers appear, but order must be (10,7) to match (A,B). Graphs of paired patterns help visualize ordering errors. Overall, such graphs reveal growth disparities, aiding in verifying claims about specific terms.

Two patterns are shown in a table and can be graphed as ordered pairs $(A, B)$ to show their relationship.

Pattern A rule: start at 1, then add 3 each time. Terms: 1, 4, 7, 10

Pattern B rule: start at 5, then add 1 each time. Terms: 5, 6, 7, 8

Which ordered pair represents the 2nd terms of the two patterns?

$(7, 6)$

$(4, 6)$

$(1, 6)$

$(6, 4)$

Explanation

The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 1 and adding 3 to get 1, 4, 7, 10, and Pattern B starting at 5 and adding 1 to get 5, 6, 7, 8. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (1,5), (4,6), (7,7), and (10,8), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show Pattern A catching up to Pattern B at (7,7) due to its faster addition rate. A common misconception is mixing terms from different positions, like pairing first A with second B as (1,6), but pairs must correspond by order. Graphs of paired patterns help visualize intersection points. Overall, such graphs reveal how patterns converge, aiding in identifying specific term relationships like the second pair (4,6).

Two students track pages read over several days using two patterns.

Pattern A rule: start at 3, then add 4 each time. Terms: 3, 7, 11, 15

Pattern B rule: start at 2, then add 5 each time. Terms: 2, 7, 12, 17

Pair the terms in order to make ordered pairs $(A, B)$.

Which ordered pair represents the 3rd terms of the two patterns?

$(15, 17)$

$(12, 11)$

$(7, 12)$

$(11, 12)$

Explanation

The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 3 and adding 4 to get 3, 7, 11, 15, and Pattern B starting at 2 and adding 5 to get 2, 7, 12, 17. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (3,2), (7,7), (11,12), and (15,17), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show the relationship between the patterns, with the third point (11,12) directly representing the third terms. A common misconception is swapping the order in pairs, like thinking (12,11) is correct, but ordered pairs must follow the (A,B) format. Graphs of paired patterns help visualize how values align at specific positions. Overall, such graphs reveal equality points or differences, aiding in identifying specific term pairs like the correct (11,12).

5

A science club records two growing patterns.

Pattern A rule: start at 2 and multiply by 2 each time. Terms: 2, 4, 8, 16, 32

Pattern B rule: start at 3 and add 3 each time. Terms: 3, 6, 9, 12, 15

Corresponding terms are paired as ordered pairs $(x,y)$ with $x$ from Pattern A and $y$ from Pattern B, and then graphed in the first quadrant.

Which statement best explains why one pattern grows faster than the other?

Pattern A grows faster because it multiplies by 2 each time, while Pattern B only adds 3 each time.

Pattern B grows faster because it starts at 3, which is greater than 2.

Pattern B grows faster because adding is always faster than multiplying.

Pattern A grows faster because it starts at 2, and starting smaller makes it grow faster.

Explanation

Patterns can be compared and graphed to determine which grows faster and why. To generate terms, follow the rule, such as multiplying by 2 from 2 to get 2, 4, 8, 16, 32 or adding 3 from 3 to get 3, 6, 9, 12, 15. Ordered pairs are formed using corresponding terms, with x from the multiplying pattern and y from the adding one. The graph illustrates the relationship by showing exponential growth outpacing linear growth over time. A misconception is thinking a higher starting point always leads to faster growth, but multiplication can accelerate quicker. Graphs visualize these dynamics effectively. They help in understanding long-term pattern behaviors and comparisons.

In a classroom game, students make two number patterns.

Pattern A rule: start at 2 and add 3 each time. Terms: 2, 5, 8, 11, 14

Pattern B rule: start at 4 and add 2 each time. Terms: 4, 6, 8, 10, 12

Pair the 1st terms, 2nd terms, 3rd terms, and so on to make ordered pairs $(x,y)$ where $x$ is from Pattern A and $y$ is from Pattern B. These ordered pairs can be graphed on a coordinate grid to show the relationship.

Which ordered pair represents the 4th terms of the two patterns?

$(8,10)$

$(10,11)$

$(14,10)$

$(11,10)$

Explanation

Patterns can be compared and graphed to visualize their relationships and growth rates. To generate pattern terms, begin with the starting number and repeatedly apply the rule, such as adding 3 to get 2, 5, 8, 11, 14 for Pattern A or adding 2 to get 4, 6, 8, 10, 12 for Pattern B. Ordered pairs are formed by matching corresponding terms, like taking the 4th term from Pattern A as x (11) and from Pattern B as y (10) to make (11,10). The graph shows the relationship by connecting points that may form a line, revealing how the patterns progress together. A common misconception is confusing the order of x and y, but x should consistently come from the first pattern and y from the second as defined. Graphs help in seeing trends, such as one pattern catching up to the other. Overall, graphing paired patterns aids in predicting future terms and understanding their interplay.

7

Two patterns represent the number of beads in two necklaces.

Pattern A rule: start at 6 and add 1 each time. Terms: 6, 7, 8, 9, 10

Pattern B rule: start at 2 and add 3 each time. Terms: 2, 5, 8, 11, 14

Pair corresponding terms to make ordered pairs $(x,y)$ where $x$ is from Pattern A and $y$ is from Pattern B. These pairs can be graphed to show relationships.

Choose one correct relationship description.​​

Each time Pattern A increases by 3, Pattern B increases by 1.

Each time Pattern A increases by 1, Pattern B increases by 3.

Each time Pattern A increases by 2, Pattern B increases by 3.

Each time Pattern A increases by 1, Pattern B increases by 1.

Explanation

Patterns can be compared and graphed to describe their incremental relationships. Generating terms involves adding the given amount each time, like adding 1 to 6 for 6, 7, 8, 9, 10 or adding 3 to 2 for 2, 5, 8, 11, 14. Ordered pairs use x from Pattern A and y from Pattern B, such as (6,2) or (7,5). The graph shows the relationship by plotting points that reflect the differing rates, like x up by 1 and y up by 3. A misconception is assuming equal increases, but rates can vary as here. Graphs visualize these ratios clearly. They help generalize pattern interactions for predictions.

8

Two patterns show the number of stickers collected each week.

Pattern P rule: start at 5 and add 2 each time. Terms: 5, 7, 9, 11, 13

Pattern Q rule: start at 1 and add 4 each time. Terms: 1, 5, 9, 13, 17

A student pairs corresponding terms to make ordered pairs $(x,y)$ where $x$ is from Pattern P and $y$ is from Pattern Q, and then graphs them.

Which claim about the patterns is incorrect?​

The ordered pair for the 4th terms is $(13,11)$.

On the graph, $x$-values come from Pattern P and $y$-values come from Pattern Q.

The third ordered pair is $(9,9)$ because the third terms are both 9.

The first ordered pair is $(5,1)$ because the starting values are 5 and 1.

Explanation

Patterns can be compared and graphed to identify inaccuracies in pairing or claims. Generating terms requires applying the rule consistently, like adding 2 to 5 for 5, 7, 9, 11, 13 or adding 4 to 1 for 1, 5, 9, 13, 17. Forming ordered pairs involves assigning x to Pattern P's terms and y to Pattern Q's, such as (11,13) for the 4th terms. The graph shows the relationship by aligning points that demonstrate where patterns intersect or diverge. A misconception is claiming reversed pairs like (13,11) for corresponding terms, but the order must follow the pattern assignment. Graphs help spot such errors visually. They generalize relationships by showing trends across multiple terms.

9

A student makes two patterns with counters.

Pattern M rule: start at 3 and add 3 each time. Terms: 3, 6, 9, 12, 15

Pattern N rule: start at 2 and add 5 each time. Terms: 2, 7, 12, 17, 22

Pair the corresponding terms to make ordered pairs $(x,y)$ where $x$ is from Pattern M and $y$ is from Pattern N. These pairs can be graphed to compare the patterns.

Which statement about the ordered pairs is correct?

The ordered pairs are $(3,7)$, $(6,12)$, $(9,17)$, $(12,22)$, $(15,27)$.

The ordered pairs are $(6,2)$, $(9,7)$, $(12,12)$, $(15,17)$, $(18,22)$.

The ordered pairs are $(2,3)$, $(7,6)$, $(12,9)$, $(17,12)$, $(22,15)$.

The ordered pairs are $(3,2)$, $(6,7)$, $(9,12)$, $(12,17)$, $(15,22)$.

Explanation

Patterns can be compared and graphed to highlight their corresponding terms and trends. To generate terms, use the rule from the starting point, such as adding 3 to 3 for 3, 6, 9, 12, 15 or adding 5 to 2 for 2, 7, 12, 17, 22. Ordered pairs are created by combining matching terms, with x from Pattern M and y from Pattern N, resulting in (3,2), (6,7), (9,12), (12,17), (15,22). The graph reveals the relationship through plotted points that may show a linear trend reflecting the additive rules. A misconception is reversing the pairs, but correct ordering matches the patterns as specified. Graphs assist in comparing growth visually. They enable better analysis of pattern similarities and differences.

During a reading challenge, Pattern P starts at 3 and follows the rule “add 2.” Pattern Q starts at 6 and follows the rule “add 4.”

Generated terms:

  • Pattern P: 3, 5, 7, 9, 11
  • Pattern Q: 6, 10, 14, 18, 22

A student pairs corresponding terms to make ordered pairs $(P, Q)$ and graphs them in the first quadrant.

Which claim about the patterns is incorrect?

The fourth ordered pair is $(9, 14)$.

The third ordered pair is $(7, 14)$.

In every ordered pair, the second number is greater than the first number.

The first ordered pair is $(3, 6)$.

Explanation

Patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate pattern terms, start with the initial value and repeatedly apply the rule, such as adding 2 to 3 for Pattern P to get 3, 5, 7, 9, 11, and adding 4 to 6 for Pattern Q to get 6, 10, 14, 18, 22. Form ordered pairs by matching the nth term of Pattern P with the nth term of Pattern Q, like (3,6), (5,10), (7,14), (9,18), and (11,22). The graph shows the relationship by plotting these points, demonstrating Q growing faster and always larger than P. A common misconception is misidentifying pairs, such as claiming the fourth is (9,14) instead of (9,18), which is incorrect. Graphs help visualize how patterns evolve relative to each other over multiple terms. Overall, graphing paired patterns illustrates trends like convergence or divergence, aiding in predicting future relationships.
