The "Make a Ten Strategy" is a mathematical approach where you add or subtract numbers by first making a sum of ten, which simplifies calculations. This strategy involves changing one of the numbers in an addition problem to create the number 10 (or a multiple of 10), making the calculation easier to perform mentally. For example, when adding 7 + 6, we can take 3 from 6 and add it to 7 to make 10, then add the remaining 3 to get 13. This technique helps children develop number sense and mental math skills by leveraging the decimal system's base of 10.

The Make a Ten Strategy can be applied in different contexts including single-digit addition, two-digit addition, and subtraction. For addition with one-digit numbers, you identify how much more one number needs to make 10, and then decompose the other addend accordingly. With two-digit numbers, you can extend the strategy to multiples of ten (like 20, 30, 40). For subtraction, you can break down the subtrahend strategically to create an intermediate step of 10, making the calculation more manageable.

Examples of Make a Ten Strategy Example 1: Adding single-digit numbers using the Make a Ten Strategy Problem:

Calculate 9 + 4 using the Make a Ten Strategy.

Step-by-step solution:

Step 1: Identify how much more the first number needs to make 10. Since 9 + 1 = 10, we need 1 more to make 10.

Step 2: Break down the second number to provide what's needed for the first number. We can split 4 into 1 + 3 (where the 1 will help us make 10).

Step 3: Rearrange the addition problem. 9 + 4 = 9 + (1 + 3) = (9 + 1) + 3 = 10 + 3 = 13

Step 4: Calculate the final sum. 10 + 3 = 13

This approach is easier because working with 10 simplifies our calculations.

Example 2: Adding two-digit numbers using the Make a Ten Strategy Problem:

Mike bought a book for $47 and a pen for $15. How much money did he spend in all?

Step-by-step solution:

Step 1: Identify the addition problem. Money spent = $47 + $15

Step 2: Look at the ones digits and determine what's needed to make the next ten. For 47, we need 3 more to reach 50 (the next multiple of 10).

Step 3: Break down the second number to provide what's needed. We can split 15 into 3 + 12 (where the 3 helps us reach 50).

Step 4: Rearrange and solve the addition. $47 + $15 = $47 + $3 + $12 = $50 + $12 = $62

Step 5: State the final answer. Mike spent $62 in total.

This method avoids the traditional column addition and makes mental calculation much easier.

Example 3: Using the Make a Ten Strategy for subtraction Problem:

Calculate 14 - 8 using the Make a Ten Strategy.

Step-by-step solution:

Step 1: Identify what to subtract from 14 to get to 10. 14 - 4 = 10, so we need to subtract 4.

Step 2: Break down the number we're subtracting into useful parts. We can split 8 into 4 + 4 (where 4 is what we identified in Step 1).

Step 3: Perform the subtraction in two steps. First: 14 - 4 = 10 (reaching the friendly number 10) Second: 10 - 4 = 6

Step 4: Write the complete solution. 14 - 8 = 14 - (4 + 4) = 14 - 4 - 4 = 10 - 4 = 6

This approach breaks down the subtraction into smaller, more manageable steps by utilizing 10 as a friendly number.
