Thirty particles fall from above. Use the repelling particle to nudge them into the correct box depending on whether they contain a square number or a prime number. This game is addictive - three thumbs up!
Choose your wheel and answer the questions. The wheels include tables, rounding, squares, and many others.

Page 1 of this flipchart contains 10,000 dots - 10 rows of 10 squares, where each square consists of 10 rows of 10 dots. 10 x 10 x 10 x 10 = 10,000.
On page 2, I shrank the big square of dots on page 1, and then made a square that consists of 10 rows, each containing 10 of these squares, or 100 squares altogether. 10,000 x 100 = 1,000,000! So this page actually contains 1 million dots.
If you use the ActivStudio zoom tool, you can zoom in enough to see the original dots. Interesting side note - the file is only 10.02 KB.
A really really cool interactive game to practise number properties. Thirty particles fall from above. Use the repelling particle to nudge them into the correct box depending on whether they contain a square number or a prime number.
Three thumbs up!
