COMPOSING AND DECOMPOSING SHAPES -ACTIVITY WORKSHEETS
Free worksheets on composing and decomposing shapes would definitely give elementary kids a clear understanding on 2 D, 3 D and composite shapes which form the basis of Geometry. Other topics that can addressed with the help of composing and decomposing shapes are fractions, proportions, area, and perimeter. Total surface area and volume are two important concepts when you deal with 3 D shapes.
Composing is combining or joining two or more shapes to form a new shape. Decomposing, as the name implies, is the splitting or breaking a shape into two or more shapes. An example is illustrated below
