The most common double-doubles combinations are points and rebounds for big men and points and assists for guards.
What is the doubling strategy in math?
The Using 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 a doubles fact for 6 7?
The number 6 is one less than 7. So, we can write 6 as 7 – 1. So, the addition 7 + 6 can be shown as: We already know the double of 7 is 14.
Which doubles fact will help you find 5 6?
If they know 5 + 5 = 10, they know that the sum of 5 + 6 will be one more. Thus, 5 + 6 = 11. Practice solving other doubles-plus-one facts together, such as 3 + 4, 7 + 8, and 9 + 8. Make sure children write down or say the doubles facts that can help them solve the equations.
What is the doubles plus one fact for 7 7?
Now, we have to use this fact for 7 + 7. So, we consider 7 + 8 = 15. Hence, the double plus one facts for 7 + 7 is 7 + 8 = 7 + 7 + 1.
What is a double plus 2 fact?
Double the smaller addend and count-on two more. OR The number between the two numbers being added – double it. For example: 4+6, the number between 4 and 6 is 5, double it and get 10. So, 4+6=10.
What is a double helper fact?
Helper facts are facts that we already know and that we can use to help us find answers to facts we may not know. Because we learned the doubles facts (such as 2 + 2 = 4 and 3 + 3 = 6) in first grade, we can use them now as helper facts. For example, knowing 4 + 4 = 8 can help us figure out the answer to 4 + 5.
What is a make 10 fact?
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 is a double ten frame?
Two side-by-side ten frames. Double ten frames can be used to represent numbers 0–20 as well as addition facts in a variety of ways and are particularly useful for encouraging children to develop addition fact strategies such as near doubles and making 10.
What is a turn around fact?
A turn around fact is a multiplication or an addition fact in maths, which you’re able to ‘turn around’ or reverse the addends or factors and still get the same answer.
What is the turn around rule?
A rule that says you can add two numbers in either order and get the same result (for example, 3 + 5 = 8 and 5 + 3 = 8).
What is the turn around rule for multiplication?
numbers may be multiplied in either order and the product will remain the same. For example: 2 × 5 = 10 and 5 × 2 = 10. Knowing this rule can help children multiply more easily.
What is a turn around phrase math?
Turn around words are words that cause the number to be written after the variable. The turn around words are “than” and “from”. Anyone who teaches algebra I knows that students have trouble writing an algebraic expression for “4 less than 3 times a number” or “13 subtracted from a number is 20.”
What is the key word for the commutative property?
The word “commutative” comes from “commute” or “move around”, so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is “a + b = b + a”; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is “ab = ba”; in numbers, this means 2×3 = 3×2.
What is a coefficient in math?
A coefficient is a number multiplied by a variable. Examples of coefficients: In the term 14 c 14c 14c , the coefficient is 14.
Is 3 a coefficient?
The values 3 and 5 in the first equation are coefficients of x , a variable. In the second equation, if a and b are constants, then a is a coefficient of x 3 , and b is a coefficient of y 2 . 2) In physics and engineering, a coefficient is a quantitative expression of a specific property of matter, or of a phenomenon.
Why is it called a coefficient?
Coefficient: A coefficient is a number, or variable, that is multiplies a variable term. Even though they are variables, the represent some constant, but unknown value unlike the variable x which is variable of the expression. The origin of the word reaches back to the early Latin word facere, to do.
What is the coefficient of 20?
Answer. Answer: the coefficient of 20 is number itself..
Can a coefficient be negative?
Coefficients are numbers that are multiplied by variables. Negative coefficients are simply coefficients that are negative numbers. An example of a negative coefficient would be -8 in the term -8z or -11 in the term -11xy. The number being multiplied by the variables is negative.

What does constant mean in math?
A constant, sometimes also called a “mathematical constant,” is any well-defined real number which is significantly interesting in some way. A function, equation, etc., is said to “be constant” (or be a constant function) if it always assumes the same value independent of how its parameters are varied. …
