QuestionFact family includes . Find the other three facts and draw models for them. Select from options A-H.
Studdy Solution
STEP 1
Assumptions1. The given fact is
. A fact family in mathematics is a set of related addition and subtraction facts that use the same numbers.
3. The other members of the fact family are obtained by rearranging the numbers in the given fact and changing the operation from addition to subtraction or vice versa.
STEP 2
First, let's identify the other members of the fact family for the given fact .The other members of this fact family are1. Reversing the order of addition
2. Subtracting the first number from the sum
. Subtracting the second number from the sum
STEP 3
Now, let's check which of the options A to H match the members of the fact family we identified.
Option A is a member of the fact family.
Option B is not a member of the fact family.
Option C is not a member of the fact family.
Option D is not a member of the fact family.
Option is a member of the fact family.
Option F is a member of the fact family.
Option G is not a member of the fact family.
Option H is not a member of the fact family.
STEP 4
For part b, we need to draw number line models for each of the number facts in part a.1. For the fact , start at0, make a jump of3 to reach3, then make a jump of9 to reach12.
2. For the fact , start at0, make a jump of9 to reach9, then make a jump of3 to reach12.
3. For the fact , start at12, make a jump of -3 (backwards) to reach9.
4. For the fact , start at12, make a jump of -9 (backwards) to reach3.
The number fact that corresponds to the question mark in each graph is the fact that is represented by the jumps on the number line.
