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.
