Maths Activity 1
- Last week you had to add 2 four-digit numbers on your place value grid using counters and then column addition. This week we are going to do the same but we might need to exchange our counters.
3,356 + 2,435
We know how to represent the numbers on our place value grid. When we add our ones we have 11, we can exchange 10 of our ones for a 10 counter.
Do we need to exchange any 10s? 100s? or 1000s?
When we add them up we get 5,791.
Use this method and the counters to calculate:
3,356 + 2,437
3,356 + 2,473
3,356 + 2,743
