Panther and Leopard Group Maths Week 9!
Welcome to week 9 of your maths home learning!
This week we’ll be revisiting addition problems.
ROCK STARS!! Don’t forget to complete 20 minutes of Times Tables Rockstars a day to keep up your great times tables work!
Monday 8th June 2020WALT: solve addition problems using estimates.
When we estimate the answer to a problem we have to first round the numbers to a sensible
amount. This could be to the nearest 10, 100 or 1000.
You will need to remember our rounding rhyme!
Today, you will need to decide what you are going to round your number to (nearest 10, 100 or 1000) in
order to achieve the most accurate estimate but still keep the calculation simple. An estimate should be quick
and easy to calculate. Perhaps have a try with the first problem before you decide how to solve the rest.
Monday 8th June 2020WALT: solve addition problems using estimates. Remember, estimate first, then check your answer using column addition. If your estimate is far
away from your answer then you have made a mistake and will need to go back and check
which of your calculations, rounding, is incorrect!
1. 1432 + 3675 =
2. 3619 + 6120 =
3. 4313 + 9278 =
4. 6428 + 2189 =
5. 5682 + 3434 =
Challenge: can you solve this problem by rounding to the nearest 10, 100 and 100?
1245 + 6720 =
Which estimate is the most accurate? Is the best one? Explain your answer.
Answers: I decided to round mine to the nearest hundred so my estimate would be more accurate than the nearest 1000 but easier to calculate quickly than the nearest ten. You may have chosen to round to the nearest 10 or 1000 and that’s okay too.
