Set of Base 10 Manipulatives
Base Ten Blocks provide a spatial model of our base ten number system. The smallest blocks, cubes that measure 1 cm on a side, are called units. The long, narrow blocks that measure 1 cm by 1 cm by 10 cm are called rods. The flat, square blocks that measure 1 cm by 10 cm by 10 cm are called flats. The size relationships among the blocks make them ideal for the investigation of number concepts.
Base Ten Blocks are especially useful in providing students with ways to physically represent the concepts of place value and addition, subtraction, multiplication, and division of whole numbers. By building number combinations with Base Ten Blocks, students ease into the concept of regrouping, or trading, and can see the logical development of each operation. The blocks provide a visual foundation and understanding of the algorithms students use when doing paper-and-pencil computation.
6 flats (100s)
15 rods (10s)
25 unit cubes (1s)
