Maths: written and mental ways of multiplying

Today we practised a written way of multiplying. In the first example we started by doing 3 x 4 = 12. Then we did 20 x 4 = 80 on the next line. Finally we added the two answers. The second example was done in the same way.

For homework please do the sheet I gave you, which is all about mental multiplying. We learned ways of multiplying mentally earlier in the week. Follow the steps on the board above and you will see how to do the sheet. First separate the tens and units. Then multiply both, and then add the two answers. Finally copy the question and put the answer with it.
