Overview

Students will look at a number and determine how many rows and columns it creates in a Lego brick to create equal shares.

This activity results from the ALEX Resource Gap Project.

Mathematics (2019) Grade(s): 3

MA19.3.2
Illustrate and interpret the quotient of two whole numbers as the number of objects in each group or the number of groups when the whole is partitioned into equal shares.

Vocabulary

Partitive division
Measurement division
Missing factor
Factor
Quotient
Partition
Product
Divisor
Dividend
Equal share

Knowledge

Students know:

that division is related to multiplication in terms of finding a missing factor. The missing factor being either the number of groups or the number of items in each group.

Skills

Students are able to:

Interpret quantities in a division situation as the number of objects in each groupor the number of equal groups.
Use a model or drawing to illustrate a quotient.
Write word problems for division context involving equal groups and fair shares.

Understanding

Students understand that:

a division expression represents either the number of objects in each group when the total number is partitioned evenly into a given number of groups or the number of groups when the total number is partitioned into groups that each contain a given number.

Learning Objectives

Students will match a quotient with a Lego array on a Lego brick and find the corresponding row, column and the total number of pips that relate. Students will then write a corresponding equation to the array.

Activity Details

Share with students that they will be playing a matching game with cards and Legos.

The teacher holds up a brick. Teacher asks students to name the brick (ie. 2x3). Teacher asks, Why do we call it a 2x3 brick? Student response would be because there are 2 rows and 3 columns. Practice with several different bricks.

Pass out a Lego Arrays Matching Game sheet to all students. Go over the directions and play a practice round with the class.

* Draw a card.

* Find a Lego brick that has the same number of pips on the brick as the quotient card.

* Draw the Lego brick on your paper.

* Write the number of rows, columns, and pips on the next column that corresponds with the Lego brick.

* Write a division equation to match.

Give students a partner and a set of cards per group. Allow students time to play the game.

Assessment Strategies

Answer sheet serves as assessment check.

Background / Preparation

Print out one Lego array game sheet per student.

Print out one set of quotient cards per group.
