Maths revision

Today we completed the last few revision points in time for tomorrow's maths exam. We started with co-ordinates. To do co-ordinates we need to look at rows and columns. We put the column first, then the row, as you can see on the board above.

Next we looked at the equals sign. What does the equals sign mean? It means is the same as. It does not mean changes into or becomes. If the example at the bottom of the board above looks OK to you, then you are reading the equals sign correctly.

Here are more examples that use the equals sign. Can you find the numbers that go into the boxes? 2 goes into the top box, because both sides make 7. 10 goes in the bottom box, because both sides make 16.

Lastly we looked at reading scales. First we have to find what each little space on the scale means. 50 is the little line half way between 0 and 100. We see that there are 5 spaces between 0 and 50. That means each space is 10g.

At home please look through the last few revision sheets. You do not need to do every question. Just make sure that you understand how to do them.
