If you are just joining us back after the Easter holidays, welcome back. I thought it would be a good idea to revise our written calculations strategies for the 4 operations this week. Mainly because we have been missing out on our arithmetic lessons.
Today we will look at ADDITION
Here are some addition calculations to complete mentally as a warm-up.
1. 23 + 24
2. 26 + 35
3. 37 + 19
4. 56 + 35
5. 67 + 43
So here is a video reminder of how to complete a column addition calculation with exchanges, just like we have practised in class (It says year 3, but it's suitable for year 4):
Try the method now with these calculations:
34 + 67
234 + 266
357 + 316
414 + 287
1532 + 1289
£24.37 + £53.56
Review - Check your answers using a calculator. Most phones and Windows PCs have a built in calculator!
