Use place value understanding to round whole numbers to the nearest 10 or 100.
My students love mystery tasks! There are several cards in each set, and each set has a clue to help find the solution. There are 14 sets of mystery cards. These can be used in multiple ways. I recommend choosing a couple to model with the class, then letting students solve them in groups or while working together in centers. I have seen good discussion among students!
When working in groups or in a center, I put all the clues for the same number in an envelope. Students in the group pass out the clues and take turns reading them aloud. As they are read, students list all possible solutions and eliminate solutions based on other clues. After reading all the clues, they should review them to check their answer meets all criteria.
Some mystery numbers will have multiple solutions, while others will have just one. The important part of the lesson is the discussion and questions.
This activity contains:
* note to teachers giving a suggestion for how to use these and including suggested questions
* 14 mystery numbers labeled by letter
* title page to use for centers
* student document to record solutions
I hope this is helpful! I welcome your comments and suggestions. If you have a question, please leave it on my TPT page. I am happy to answer any questions!
