Lesson 3-5 Example Example 2 Draw a model of 15 ÷ 3. 1.What is the divisor? 3 Draw circles.

Lesson 3-5 Example Example 2 Draw a model of 15 ÷ 3. 2.What is the dividend? 15 Use tally marks to divide the 15 into 3 groups. Place a tally mark in each circle as you count until you have drawn 15 tally marks.

Lesson 3-5 Example Example 2 Draw a model of 15 ÷ 3. 3.How many tally marks are in each circle? 5 Write the problem with the quotient. 15 ÷ 3 = 5

Lesson 3-5 Example Example 2 Draw a model of 15 ÷ 3. 4.Check your work. 3 × 5 = 15
