The computer has selected a fraction at random. Your job is to determine the fraction by guessing. The computer will tell you if you are too high or too low. A great way for students to practice ordering fractions.

Four activities to support the teaching and learning of Factors and Multiples.

The Factor Game
This is the classic factor game.

Highest Common Factor Game
A great game for practising highest common factors.

Factors and Multiples Puzzle (from NRich)
A fantastic whole number activity from the NRich website. Factors, multiples, square numbers, triangular numbers, etc.

Juniper Green
A great game for consolidating factors and multiples.

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.

There is a cool puzzle at the Nrich website called the Factors and Multiples Puzzle, which can be found on-line at http://nrich.maths.org/public/viewer.php?obj_id=5448

I have created a flipchart to support the use of this puzzle in the classroom. Enjoy!

Below are two TI-Nspire documents from Spencer Williams that show visually the operations of adding and subtracting fractions. There is also a pdf file to support the use of these in the classroom. Thanks, Spencer, for sharing these.
