Skills Covered

  • Share equally: how many in each group
  • Make equal groups: how many groups
  • Name the dividend, divisor and quotient
  • Divide with an array
  • Divide with equal jumps back to 0
  • Tell the two kinds of division stories apart

How to Use This Pack

Five pages on the two meanings of division, with divisors from 2 to 10. On page 1 students share a row of pictures equally on plates or in bags: they draw the share and write how many each one gets, such as 12 shared on 3 plates is 4 on each plate. Page 2 turns it around: circle groups of a given size, such as groups of 3 in 24 rubber ducks, and write how many groups. Page 3 has sharing and grouping pictures to write a division sentence for, then a table where each row needs its dividend, divisor, quotient or whole sentence filled in. Page 4 divides with arrays (24 in rows of 6: how many rows?) and with jumps back to 0 on a number line, where the number of jumps is the quotient. Page 5 has six stories: students circle whether each asks how many in each or how many groups, then write the division sentence. Each page starts with a worked example.

In the Classroom

Act out both meanings with the same 12 counters. First share them among 3 students: each gets 4, so 12 ÷ 3 = 4 asks how many in each. Then hand out groups of 3 until the counters run out: 4 students get a group, so 12 ÷ 3 = 4 asks how many groups. Write both on the board and ask what is the same and what is different. Before page 4, line up 20 students' steps on a floor number line and jump back by 5s to 0 together.

At Home

Divide snacks both ways. Share 15 crackers among 3 people and count how many each gets, then put 15 crackers into piles of 5 and count the piles. Ask which question each way answered: how many in each, or how many groups.

Tips for Success

  • Sharing: you know how many groups, and you find how many go in each
  • Grouping: you know how many go in each group, and you find how many groups
  • In 12 ÷ 3 = 4, 12 is the dividend, 3 is the divisor and 4 is the quotient
  • Hand things out one at a time so every group stays equal
  • On a number line, count the jumps back to 0: that is the quotient

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 3.OA.A.2 Understand a quotient as either the size of each equal share or the number of equal groups, such as 24 ÷ 6.
  • 3.OA.A.3 Solve story problems about equal groups, arrays and measurements by multiplying or dividing within 100, using drawings and equations.
  • 3.OA.B.6 Treat division as finding a missing factor: solve 35 ÷ 5 by asking what times 5 equals 35.
  • 3.OA.D.8 Solve two-step story problems with +, −, × and ÷, using a letter for the missing amount, and check answers by estimating or rounding.

Division: Sharing and Grouping

3rd Grade

Division as sharing things equally and as making equal groups, with the dividend, divisor and quotient named. Students share pictures on plates and in bags, circle equal groups, write division sentences, divide with arrays and jumps back to 0, and sort stories by what they ask.
