Mental math double plus 2 strategy

It seems like you’re looking for information about the “double plus 2”Mental math double plus 2 strategy, possibly with a heading. This mental math strategy is a technique used to quickly calculate the result of doubling a number and then adding 2 to it. Here’s an explanation with a heading:

Why use Mental Math Double Plus 2 Strategy?

But why is it important? Because mental math relates to NUMBER SENSE: the ability to manipulate numbers in one’s head in various ways in order to do calculations. And number sense, in return, has been proven to predict a student’s success in algebra.

What is the Mental Math Double Plus 2 Strategy for Teaching Doubles Addition?

The Near Doubles strategy involves decomposing one addend to make a double with the other addend. For example 7 + 8 is the same as 7 + 7 plus 1 more. Double ten frames are great for exploring the strategy. Have students build each addend on a different ten frame using two-color counters.

What is the Mental Math Jump Strategy?

The jump strategy for addition is a math strategy that helps students break down addition problems into smaller, more manageable steps. This strategy involves “jumping” forward on a number line to add or skip count to find the total.

What is the Near Doubles Strategy?

We use this strategy when adding two consecutive numbers, in other words two numbers that follow each other. This is where students use their knowledge of doubles to work out the answer. For example, the problem might be 5 + 6 =

This is the same as 5 + 5 + 1 = 11 or 6 + 6 – 1 = 11.

Double Plus 2 Mental Math Strategy

The “Double Plus 2” mental math strategy is a quick and efficient method for performing mental calculations. It involves two simple steps:

Double the Number: Begin by doubling the number you want to work with. This means multiplying it by 2.
Add 2: After doubling the number, simply add 2 to the result.

Formula: Result = (2 * Number) + 2

Example: Let’s say you want to calculate 7 * 2 + 2 using the “Double Plus 2” strategy.

Double the number 7: 7 * 2 = 14
Add 2 to the result: 14 + 2 = 16

So, 7 * 2 + 2 = 16.

Where $x$ is the original number you want to add 2 to. For example:

If you want to add 2 to 5 using the “double plus 2” strategy:
1. Double 5: $2 \times 5 = 10$
2. Add 2 to 10: $10 + 2 = 12$

So, 5 + 2 = 12 using the “double plus 2” strategy.

This mental math strategy is especially useful for quickly estimating or calculating simple arithmetic operations in your head. It can be applied to various numbers and is handy for improving mental math skills.

What is an example of a double addition?

When we add two of the same number, we add using the “doubles fact”. For example, 1 + 1 and 2 + 2 are both doubles facts. 4 + 4 = 8 is a doubles fact. Doubles fact can help us know other additional strategies like doubles plus one.

What Are Doubles Plus One?

Using a strategy-based approach to adding and subtracting helps to master addition and subtraction facts. One such strategy we use to understand addition or subtraction facts is the doubles strategy or fact.

When we add two of the same number, we add using the “doubles fact”.

For example, 1 + 1 and 2 + 2 are both doubles facts.

Look at the example below:

4 + 4 = 8 is a doubles fact. Doubles fact can help us know other additional strategies like doubles plus one. This strategy is used in the addition of two consecutive numbers, like 2 + 3. Here, we break one of the addends to make a double with the other addend.

How to Add Numbers With the Mental Math double Plus 2 Strategy?

Knowing Mental Math double Plus 2 Strategy facts lays a foundation for solving doubles plus one addition. Let’s begin by adding two consecutive numbers using this method.

For example, consecutive numbers 8 and 9 have been added using the strategy.

We know that 8 + 8 is 16, so 8 + 9 = 17

Let’s look at another example of this strategy. Use the image to solve 4 + 5

We know that 4 + 4 = 8, so 4 + 5 = 4 + 4 + 1 = 8 + 1 = 9
