Divide and Share!
Ms. Vega has 96 new books to share equally among 4 classrooms. Can division help her share them fairly?
4th Grade MathStep 1: Divide the Tens
The number 96 has 9 tens and 6 ones. Each block above is worth one ten. First, divide the 9 tens among the 4 classrooms. What happens?
Step 2: Divide the Ones
The leftover ten becomes 10 ones. Add the 6 ones: 10 + 6 = 16 ones. The array shows those 16 ones in 4 equal rows, one row per classroom. How many ones does each classroom get?
Let's Remember
Step 2: Regroup leftovers into the next place.
Step 3: Keep dividing until only a remainder is left.
In 96 ÷ 4 = 24, the 96 is the dividend, the 4 is the divisor, and the 24 is the quotient.
See It on a Number Line
Division makes equal jumps. Four jumps of 24 travel from 0 all the way to 96. That proves 96 ÷ 4 = 24, because 4 × 24 = 96. Multiplication and division are partner operations!
Watch Out! The Missing Zero
Think: 3 × 24 is only 72. Leo's answer is way too small! When a place gets nothing, you must write a zero in the quotient. What is 612 ÷ 3 really?
