this week we have been looking at adding and subtracting numbers that are near multiples of 10s. For example 29 is near 30. 42 is near 40 . Can you solve the following problems using the strategies we used in class ? Remember we used number lines . Remember to use jumps of 10s .Read the problem to make sure you are using the correct calculation of adding or subtracting . 1/ 67+31 2/ 65+49 3/ 104+41 4/ 247+59 5/ 78-49 6/ 96-41 7/ 113-59 8/ 126-61 Remember i want to see how you solved the problem using a number line .
