Let's learn about triangles! First, watch the video from Ms. Elaine on page 1. Then, go to page 2 where you will see different shapes. Tap You need to look for the triangles. Remember to find shapes that have 3 SIDES and 3 VERTICES! Move the triangles into the box above. And keep the other shapes below. Supporting Adults: As this stage, there is no expectation that the children are easily able to identify shapes or their attributes or to use the correct vocabulary right now. You can support them by using the vocabulary of SIDE and VERTICES (or vertex for one) as well as helping them identify what a side and vertex are. (Please do not use the term corner. Please use VERTEX and VERTICES) Learning Intention: To begin to identify and describe triangles To begin to use appropriate mathematical terms to describe triangles.
