My friend George has 16 balloons, and shares them equally with me and 2 more friends. How many balloons does each friend have now?

Explain it : show how you can use repeated subtraction to find how many groups of 4 are in 16 then write the division sentence for the problem.

16-4=12 12-4=8 8-4=4 4-4=0

Sometimes drawing a picture will help you solve a problem.It will help you see the problem and perhaps the solution.

When you multiply by seven then you might follow the seven rule like for example 7x8 first multiply 2x8 which equals 16 then you multiply 5x8 which equals 40 you are going to add 40+16 which equals 56 so there’s the answer 56.

Members of the Biology Club caught 288 butterflies and 136 grasshoppers in their nets. About how many more butterflies than grasshoppers did the club catch? You can estimate by rounding. To round to a certain place, look at the digit to the right of that place. If the digit is 5 or greater, round up. If the digit is less than 5, round down. Round to the nearest hundred. Look at the digits in the tens place. There were about 200 more butterflies than grasshoppers caught. Round to the nearest ten. Look at the digits in the ones place. There were about 150 more butterflies than grasshoppers caught.

You can change numbers to make subtraction easier.

Example: 42-28 there are two ways to do 42-28 one is to add 2 to 28 now you have 30 &amp; you are left with 40 on the other hand, so now 30-40=10 so 42-28=10. (But you have to do all that in your mind when doing mental math.)

If you have 35 divided by 5. You have to subtract until you get the answer.

Blue geometrical pattern

The island of Elba has an area of 86 square miles. The island of St. Helena has an area of 47 square miles. How many square miles larger is Elba than St. Helena? You can subtract to find how many square miles larger Elba is than St. Helena. Use mental math or a hundred chart to subtract. 86-47 = 39

Multiplication is the same as repeated addition

12x12=144 12+12+12+12+12+12+12+12+12+12+12+12=144
