The Concept of 20



The Concept of 20 reproducible workbook takes the student from the concept of 10 to the concept of 20. As some children find it difficult to move over the number 10, some different strategies are used to teach the concept of 20.

• Compare, order and represent numbers from 1 to 20

• Add 1 to any number in the range of 20

• Subtract 1 from any number in the range of 20

• Gradually progress to add on or subtract 2, 3, 4, 5, 6, 7, using the aid of a
1 to 20 number line

• Learn that two tens equal 20 ones
