This week third graders started expanding on their knowledge of fractions. Pattern blocks are an extremely helpful manipulative used in many grades when talking about parts and wholes and equivalencies. We often use the hexagon as the ONE or whole, so it follows that the trapezoid is half, rhombuses are thirds and triangles are sixths. I always let the students play before using manipulative as tools. Play, as well all know, also helps us learn.
