Uses the relationship that a right triangle’s area equals half the area of the surrounding rectangle. Includes an instructional example where a rectangle has area 15 square blocks and the triangle has area 7.5 square blocks, then asks learners to compute areas for multiple numbered triangles labeled 1) through 9). Answer keys provide the corresponding block-area results for each item.","Finding the Area of Right Triangles with a Grid  \nName:  \n\n| \u003Cbr>Find the area of each triangle in blocks
