This pop up has layered mechanism based on 10 parallelograms that form stairs. Basically it is a multiplication chart in 3D. Every number has its own color, so if the color of the top and the front surface coincide it is the square number. The product of two numbers is on the front side of the step. This POP UP Multiplication Chart is perfect for the kids who do not know the principle of multiplication yet because on every step there is a number that is being added. You go one step up and add on

Multiplication Wheel is very Easy to assemble and fun to use

You can turn a clock in your classroom into a multiplication prompt. Unlike other clockfaces that usually have only 5x tables this one has 2x tables. Students can easily solve a problem having a visual support in front of their eyes.

This is another way of presentation of traditional Table of Pythagoras - It's a CIRCULAR grid, that resembles a spider's net. There is also a blank page for kids' practice. Check out for my another freebie "Find the Quotient" based on this grid.

This is a collection of three unique times tables charts in pseudo- 3D. The idea came to my mind after I made a real 3D Times tables which is a paper pop up Multiplication Table that can also be found at my store. The isometric representation gives volume to the usual times tables and also the numbers in these Times tables rise as they go up unlike the usual Table of Pythagoras where the numbers go up but they actually "go down" in space. In Pyramid, you can see the multiplicands on the top of
