# 3rd Grade Math Games

Play select games from the ST Math third grade curriculum. Concepts include multiplication, division, fractions, and more.

## How Many Legs Multiplication

Develop concept of multiplication as equal groups.
• Develop concepts and strategies for multiplication as equal groups.
• Levels begin with finding the number of shoes for one creature with 0 to 10 legs, then advance to solving multiplication expressions.
• Interpret multiplication expressions in the form 3 x 4 as 3 groups of 4.

## Division Using Arrays

Develop division concept and strategies using an area model.
• Develop concepts and strategies for division using a visual, area model.
• Levels begin with visual models, then advance to solving division expressions.
• Interpret division expressions in the form 8 ÷ 2 as 8 blocks divided into 2 rows.

## Multiplication and Division

Develop strategies for missing factor problems
• Develop strategies for finding the number of creatures needed for a given set of shoes.
• Levels begin with visual models giving a set of shoes, then advance to finding the missing factor in a visual model.
• Apply ideas of repeated addition,subtraction and division to missing factor problems.

## Alien Bridge Fractions

Represent fractions with visual models
• Develop concept and notation for unit and non-unit fractions.
• Levels begin with modeling unit fractions with area models, then advance to representing visual models with unit and non-unit fractions.
• Understand the role of denominators as dividing area into equal parts and numerator as selecting that number of parts.

## JiJi Cycle

Estimate fractions on a number line using circle models.
• Develop the concept of fractions as numbers on a number line using circle models (wheels).
• Understand that a whole wheel unrolls to measure the unit whole (distance from 0 to 1).
• Levels begin by estimating points on a number line using wholes and halves, then progress to representing points on a number line using unit fraction models.

## Inside and Around Rectangles

Find the area and perimeter of rectangles.
• Develop the concept of area as measured by squares and perimeter as measured by linear units.
• Levels begin with visual models and selecting squares or sticks for area or perimeter, then advance to creating rectangles for a given area and perimeter.
• Apply strategies for multiplication and addition to solve multi-step problems.
