This workbook will help your child develop an understanding of subtracting the numbers 1 through 5 from whole numbers up to 20. By using this book, children will be able to understand the concept of subtraction by repeatedly tracing and reciting numbers both forwards and backwards and then gradually shifting to subtracting the numbers 1 through 5.
