Fun way to learn place value. Various number combinations are presented for adding up. The numbers are chosen so as to avoid having to carry numbers over, which means the student can concentrate entirely on the concept of place value. These worksheets tackle the concept in various fun and highly visual ways, taking much of the strain out of the learning. Like all Bounce Learning Kids worksheets, these start out simple but become progressively more challenging as you work through the sheets. They provide instructions as well as testing acquired knowledge.
