Base ten blocks show what a number like 14 really is: one rod of ten cubes and four more cubes on their own. In every box the child counts the rods and writes how many tens, counts the single cubes and writes how many ones, and then writes the whole number. A small reminder above the boxes shows that a rod is ten and a cube is one.

Set Numbers to 11 to 19 for the teen numbers, where every box has one ten and some ones, or to 10 to 50 for up to five rods, round tens included. Choose four or six boxes on a page. No number repeats on a page.

Press New sheet for new numbers. The answer key prints on a second page only when you ask for it. Every sheet prints in color or black and white, on US Letter or A4. Nothing to sign up for.
