Shapes and Equal Shares

Learners name triangles, quadrilaterals, pentagons and hexagons by counting sides and angles and describe cubes by their faces. They split rectangles into rows and columns of same-size squares and count them, and split circles and rectangles into halves, thirds and fourths, discovering that equal shares of the same whole do not have to be the same shape.

  • 3 lessons
  • About 60 minutes
  • Shapes and shares check: 8 questions
  • Ways to answer: fill in the blanks, choose an answer, count, match pairs, type a number and shade a shape
