Choose a fact family to use to write your number sentences.
For the fact family of numbers: "9", "3", "12", there are four number sentences using addition or subtraction that result from this fact family.
9 + 3 = 12.
3 + 9 = 12.
12 - 9 = 3.
12 - 3 = 9.
Create a word problem to illustrate how numbers in that fact family work.
For the numbers in the fact family "3" + "9" = "12", you could create the following word problem:
Jane has 9 apples and Steve has 3 apples. Bob wants Jane's apples and Steve's apples. If Jane and Steve give Bob all of their apples, Bob have will have 12 apples.
Translate the numerals of the word problems into Spanish. Using the example above,
nine = neuve
three = tres
twelve = doce
Translate the numbers in the word problem into Spanish. This would read:
Jane has "neuve" apples and Steve has "tres" apples. Bob wants Jane's apples and Steve's apples. If Jane and Steve give Bob all the apples, Bob will have "'doce" apples.
For the other number sentences in this fact family, you can create other word problems to express the following:
3 + 9 = 12.
12 - 9 = 3.
12 - 3 = 9.
For example:
John needs to return 12 library books, but he left some library books in his school locker. He only brought 9 library books with him. Suzie volunteered to bring the other library books for him tomorrow. How many library books will Suzie have to bring tomorrow: Answer: 3.
Translated into Spanish numbers, the number sentence/word problem would be:
John needs to return "doce" library books, but he left some library books in his school locker. He only brought "nueve" library books with him. Suzie volunteered to bring the other library books for him tomorrow. How many library books will Suzie have to bring tomorrow: Answer: "Tres."
For each fact family you create, you will have four number sentences. You can create word problems for each sentence, translating the numerals into Spanish.
Continue with this procedure until you have 10 number sentences with numbers in Spanish.
