What is the make a 10 strategy?

In 1st grade, as students begin learning their basic addition facts, they apply that knowledge in a strategy known as “make a ten” to help make sense of facts that might otherwise be hard to memorize, such as 8 + 4 or 9 + 5. To use the strategy, students decompose one of the addends to make a ten from the other.

What are the sums of 10?

Number	Repeating Cycle of Sum of Digits of Multiples
9	{9,9,9,9,9,9,9,9,9}
10	{1,2,3,4,5,6,7,8,9}

Bridging through 10 is a mental Maths technique of adding two numbers whose total is greater than 10. Pupils count through to 10 then add the remainder as well.

What is the count on strategy?

Counting on means that you start with the biggest number and then count up from there. For example, to add 5+3, start with the “5” and then count up, “6, 7, 8.” This is to discourage students from counting like this: “1, 2, 3, 4, 5…..

How do I teach my bridging to 10?

Teachers will most likely teach the bridging through 10 method by giving a demonstration on the board, and then by giving the children a worksheet with number lines already drawn for them on which to work out their sums.

How do you explain 10 more and 10 less?

When 10 is added to a number, the tens digit increases by one. When 10 is subtracted from a number, the tens digit decreases by one. On a 120 chart, the number above a given number is 10 less and the number below it is 10 more.

What are examples of count on facts?
