This educational toy focuses on number place values.  It is a great assessment tool after you learn about number subitizing and how to think of numbers in groups such as using rekenreks or unit cubes and ten rods.

By thinking of numbers in groups, students strengthen counting proficiency, develop addition and subtraction strategies, and gain a better understanding of number relationships.

1. Each cube is defined as a "unit" or a "one"
2. A ten rod is made up of 10 cubes.  Put ten unit cubes side by side and place a ten rod next to it. Observe that they're the same length. Define the rod as a "ten."
3. Put 10 ten rods side by side.  This makes a square with 100 unit cubes. Show that a hundred flat is the same size, the same quantity. Define the flat as a "hundred."
4. Stack ten hundred flats together. Show that a thousand cube is the same size, the same quantity. Define the large block as a "thousand."
