Count From A Number Upwards <\/h2>\n\n\n\n

Example: 6 + 3<\/h3>\n\n\n\n

\"6+3:

Think “6 … 7, 8, 9”<\/p>\n\n\n\n

Hint: start from the larger number.<\/p>\n\n\n\n

Example: 2 + 6<\/h3>\n\n\n\n

2 + 6<\/strong> is Harder: “2 … 3, 4, 5, 6, 7, 8”<\/p>\n\n\n\n

6 + 2<\/strong> is Easier: “6 … 7, 8”<\/p>\n\n\n\n

So do 6 + 2<\/strong> instead (you get the same answer).<\/p>\n\n\n\n

Jump Strategy<\/h2>\n\n\n\n

We can also count by 2s or 10s, or make any “jumps” we want to help us solve a calculation.<\/p>\n\n\n\n

Example: 4 + 12<\/h3>\n\n\n\n
\"Jump<\/figure>\n\n\n\n

Think “4 … 14 … 15, 16”<\/p>\n\n\n\n

Adding Up To Ten<\/h2>\n\n\n\n

See if any numbers add to 10. They don’t have to be next to each other.<\/p>\n\n\n\n

Example: 7 + 8 + 3 + 2 + 5<\/h3>\n\n\n\n

7+3 is 10,<\/p>\n\n\n\n

8+2 is another 10, which makes 20,<\/p>\n\n\n\n

Plus 5 is 25<\/p>\n\n\n\n

Do The Tens Last<\/h2>\n\n\n\n

Break big numbers into Tens and Units, add the Units, then add on the Tens.<\/p>\n\n\n\n

Example: 14+5<\/h3>\n\n\n\n
\"14+5;<\/figure>\n\n\n\n

Break the “14” into Tens and Units: 10 + 4<\/p>\n\n\n\n

Add the Units: 4 + 5 = 9<\/p>\n\n\n\n

Now add the Tens: 10 + 9 = 19<\/p>\n\n\n\n

Think “4 plus 5 is 9, plus 10 is 19”<\/p>\n\n\n\n

Another Example: 14 + 12<\/h3>\n\n\n\n

Break into Tens and Units: 10 + 4<\/strong> + 10 + 2<\/strong><\/p>\n\n\n\n

Add the Units: 4 + 2 = 6<\/p>\n\n\n\n

Now add on the Tens: 6 + 10 + 10 = 26<\/strong><\/p>\n\n\n\n

Aim for Ten<\/h2>\n\n\n\n
\"Video\"\/<\/a><\/figure>\n\n\n\n

When a number is close to ten we can “borrow” from the other number so it reaches ten.<\/p>\n\n\n\n

<\/td>Example: 9 + 79 is only 1 away from 10<\/td><\/tr>
so take 1 from the 7: 9 + 1 + 6<\/strong>
and give it to the 9: 10<\/strong> + 6 = 16Think “9 plus 1 is 10 … 7 less 1 is 6 … together that is 16”<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Example: 8 + 5<\/h3>\n\n\n\n

8+2=10, so lets take 2 from the 5: 8 + 2 + 3
and give it to the 8: 10 + 3 = 13<\/p>\n\n\n\n

We can also move backwards<\/em> to ten, by making the other number bigger as needed:<\/p>\n\n\n\n

Example: 12 + 7<\/h3>\n\n\n\n

Reduce 12 by 2:  12 \u2212 2 = 10
Increase 7 by 2:  7 + 2 = 9<\/p>\n\n\n\n

12 + 7 = 10 + 9 = 19<\/p>\n\n\n\n

Compensation Method<\/h2>\n\n\n\n

“Compensation” is where you round up a number (to make adding easier) and then take away the extra after you have added.<\/p>\n\n\n\n

Example 19+16<\/h3>\n\n\n\n

It is easier to do 20 + 16 = 36<\/p>\n\n\n\n

Then take away the extra 1 (that made 19 into 20) to get: 35<\/strong><\/p>\n\n\n\n

Example 395 + 126<\/h3>\n\n\n\n

It is easier to do 400 + 126 = 526<\/p>\n\n\n\n

Then take away the extra 5 (that made 395 into 400) to get: 521<\/strong><\/p>\n\n\n\n

Double when the numbers are the same<\/h2>\n\n\n\n

Example 5 + 5 = 2 x 5 = 10<\/h3>\n\n\n\n

Double if the numbers are close, then fix<\/h2>\n\n\n\n

Example: 5 + 6 is nearly two 5s, but 6 is 1 bigger than 5, so:<\/h3>\n\n\n\n

5 + 6 = two 5s + 1 = 10 + 1 = 11<\/strong><\/p>\n\n\n\n

Example: 7 + 9 is like two 8s, but 7 is 1 smaller than 8, and 9 is 1 bigger than 8. So it is exactly two 8s<\/strong> because 1 smaller and 1 bigger cancel each other:<\/h3>\n\n\n\n

7 + 9 = “8 less 1” + “8 add 1” = two 8s = 16<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
