Nifty Number Stories

Use your fact family knowledge to solve! (You can add to subtract! You can subtract to add!)

Sophia had some butterflies in her yard!

Then 5 flew away.

Now she only sees 7 butterflies.

How many butterflies were there at first?

______ - 5 = 7 butterflies ( Think 5 + 7 =? )

You know there is a fact family where some big number is the grown up, and 7 and 5 are the kids. Let’s see. It sounds like our number model should say ? – 5 = 7. Let’s add to subtract! Add the 5 and 7 together, to find out how many butterflies were in her yard to start! You can draw a picture below, and write a number model to solve!

King Nathan had 8 knights at his castle.

King Eli had some knights, too!

Together they had 11 knights!

How many knights did King Eli have?

8 + ___ = 11 knights (Think 11 – 8 = ?)

You know there is a fact family where 8 is a kid, and 11 is the grown-up. Let’s see. We need to find out the other kid! It sounds like our number model should say 8 + ? = 11. Let’s subtract to add! Look at the total knights both kings had, and subtract King Nathan’s 8 knights, to find out how many knights King Eli has at his castle! Think about the fact family to solve the missing piece! Draw a picture if you would like!

Ava baked some pies with her mom!

Lucas baked 5 pies with his dad!

Together both families would have 10 pies for a pie party!

How many pies did Ava bake?

____ + 5 = 10 pies (Think 10 – 5 = ?)

You know there is a fact family where 5 is a kid, and 10 is the grown-up. Let’s see. We need to find out the other kid! It sounds like our number model should say ? + 5 = 10. Let’s subtract to add! Look at the total pies both kids made, and subtract Lucas’ 5 pies from that, to find out how many pies Ava was baking! Think about the fact family to solve the missing piece! Draw a picture if you would like!

Now, since we are going to study geology and explore rocks, try out these rockin’ word problems on your own! As you solve, it might help you to draw a picture, or think of the missing pieces of the fact family, and use the clues they gave you in the number story to solve it! Have fun with it, my rockin’ first graders!
