Math Grade 1 Quiz Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes-1.G.A.2

The Common Core State Standards (CCSS) for mathematics aims to ensure that students have a comprehensive understanding of various math concepts. The standard “CCSS.MATH.CONTENT.1.G.A.2” deals with shapes and their compositions. Students should be familiar with two-dimensional shapes such as rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles. They should also be aware of three dimensional shapes like cubes, right rectangular prisms, right circular cones, and right circular cylinders. In this standard, students not only recognize and name these shapes but also learn to combine them to form new, composite shapes. They also explore how they can form new shapes from these composite figures.
