A happy fox child looks at things on a desk

Long and Short

Kit has a pen, a cap, and a stick. Which one is the longest? Let's find out!

1st Grade Math

Step 1: Compare Two Things

The pen is on top. The cap is on the bottom. Line up the ends. Then compare! Which one is longer?

The pen is 6 cubes long. The cap is 3 cubes long. 6 is more than 3, so the pen is longer!

Step 2: Put Them in Order

The stick is on top. The pen is next. The cap is last. Which one is the shortest?

The cap is 3 cubes. The pen is 6. The stick is 8. The cap is the shortest. The order is: cap, pen, stick!

Let's Remember

          How to Compare Length
        
          Step 1: Line up the ends.

          Step 2: Look at the other ends.

          Step 3: See which one goes out more.

We compare the length. Line up the ends. Then they are equal at one end.

Step 3: Use Cubes to Measure

We cannot set the bat by the mop. So we measure with cubes! The bat is on top: 7 cubes. The mop is on the bottom: 9 cubes. Which one is longer?

The mop is 9 cubes. The bat is 7 cubes. 9 is more than 7, so the mop is longer. The cubes helped us compare!

Kit's Big Tip

Kit says: I cannot lift the mop up to the bat. So I measure them with cubes! Then I can compare the two.

Cubes help you see the length of things!

Your Turn!

The sock is on top. The belt is next. The bat is last. Which one is the longest?

The bat is 9 cubes. The belt is 6. The sock is 4. 9 is the most, so the bat is the longest!

Word Problem

Meg's pin is 2 cubes long. Sam's stick is 5 cubes long. Dot's bat is 8 cubes long. Which one is the shortest?

2 is less than 5 and 8. The pin is the shortest. The order is: pin, stick, bat!

How Long Is the Pen?

The pen is ? cubes long.

Count the cubes: 1, 2, 3, 4, 5, 6, 7. The pen is 7 cubes long.

Challenge Time!

The bat is longer than the string. The string is longer than the pin. Which one is the longest?

Think: the string helps you compare the bat and the pin!

The bat beats the string. The string beats the pin. So the bat beats the pin too. The bat is the longest!

Think About It

Look at your desk. What is long? What is short? Can you line up the ends and compare?

Great Work!
