• define, identify, compare, and order any rational numbers

Show how you could represent and compare the numbers 0.34 and 0.43, using base-10 blocks when:

• the cube represents 1
• the flat represents 1

Explain why -0.43 is less than -0.34

Explain where you would place each of the following numbers on the number line.

• express two-term ratios in equivalent forms

In Elisapee's class there are six girls and five boys while Bert's class has 15 boys. How many girls would there be in Bert's class if the ratio of boys to girls is equivalent in the two classes?

• represent and apply fractional percents and percents greater than 100 in fraction or decimal form and vice versa

John made a chart to illustrate percents. He started with a large 10 x 10 grid. he folded it in half and shaded half the squares. He counted the shaded squares and wrote . he then folded the unshaded part in half and shaded the new half a different colour. He coutned shaded parts and wrote . He did this three more times. Use a large grid to copy and complete John's work. Use the results from your work to show 150%, 212%, and

How could you use 10 x 10 grid sheets to represent:

The mark-up on Playstation 2 is 150%. Find the actual prices if the stores pay:
