Here are some problems to solve:
I had $1.00. I went to the store to buy 2 pencils. Each pencil cost 29 cents. How much did the pencils cost in all? How much change did I get back? Show two possible change combinations that I might have received.
Hajna baked 4 trays of muffins. Each tray held 6 muffins. She took 15 muffins to school for the bake sale and left the rest at home to share with her family. How many muffins did Hajna leave at home?
Record a number sequence of at least ten numbers where each number is four more than the previous number.
When you solve a problem leave your answer in a comment. It would be great if you’d leave a new problem for the rest of us to solve too.
Happy math!
.29+.29=.58 total, .42 back, added .02 to .58 to get to .60, then added .40 to get to the dollar.
Change, 2 pennies, 1 quarter, a dime and a nickel
Change, 42 pennies
Well done – first I am really glad that you went online to find the math challenge. Second you did a complete job of explaining your math thinking to find the total cost and to calculate the change in two different ways. Will you tell other kids about the math here?
I’m not sure but il try.
Do whatever feels like the right thing to do. I am glad you are using the blog.
