FACTS ABOUT THE BASE TEN BLOCKS.
1) Dimensions of 1 ones block = 1 cm by 1 cm by 1 cm. So, volume = 1 cm cube.
Total surface area = 6 x 1 cm sq = 6 cm sq.
2) Dimensions of 1 tens block = 10 cm by 1 cm by 1 cm. So, volume = 10 cm cube. Total surface area = 4 x 10 cm sq + 2 x 1 cm sq = 42 cm sq.
3) Dimensions of 1 hundreds block = 10 cm by 10 cm by 1 cm. So, volume = 100 cm cube. Total surface area = 4 x 10 cm sq + 2 x 100 cm sq = 240 cm sq.
4) Dimensions of 1 thousands block is 10 cm by 10 cm by 10 cm. So, volume = 1000 cm cube. Total surface area = 6 x 100 cm sq = 600 cm sq.
Because of the above facts, we can even use base ten blocks to teach other topics like measurements in mathematics and volume calculations in science.
