Area of a Right Triangle - Concept Intro - Half Squares (Level 2)

This math topic focuses on understanding how to calculate the area of right triangles using the method of counting square units. It provides practice in estimating how many one-unit squares (cm², ft², m², km²) cover the area of various right triangles. The problems include images of right triangles overlaid on grids of square units and questions asking to determine how many squares are covered by each triangle. There are multiple-choice answers for students to select from, assessing their ability to visually and numerically calculate the area of right triangles through basic counting techniques.
