Maths: addition practice and mental maths practice

This morning we practised addition, using mental methods and written methods. If we use a written method we must be sure to keep our columns straight. If we use a mental method, it is best to do each sum in two steps. Start with one of the two numbers, then add the tens. Finally add the units.
Example: 85 + 67
Start with 85 + 60 = 145 (Easy because we just have to add 6 tens to 8 tens, and leave the units the same.)
Then do 145 + 7 = 152. Done.

We also did a timed practice test for mental mathematics. We will do more of them between now and the exams. At home you can review the questions that you got wrong (and give yourself a pat on the back for the ones you got right).

Also please do the money sheet I gave you for homework. Enjoy doing your homework and make a good job of it.
