This packet is designed to help students develop reading comprehension and problem solving skills as they work with the following Common Core Math Standards:
CCSS 1.NBT.B.2: Understand that the two digits of a two-digit number represent amounts of tens and ones.
CCSS 1.NBT.B.3: Compare two two-digit numbers based on meaning of the tens and ones digits.
CCSS 1.NBT.C.5 Given a two-digit number, mentally find 10 more or 10 less than the number without having to count. Explain the reasoning used.
This pack includes:
24 number riddle cards
Everything you need to play Number Riddle Scoot
A student recording sheet
An answer sheet
These riddles can be used in many ways. For partner work, I have kids take turns choosing a card and discussing the answer with their partner. If the two partners do not agree right away, they explain their thinking and reasoning to one another. If needed, they can also “prove it” using manipulatives and/or the hundred chart (included). Once they have come to an agreement, they write their answer on the recording form. When they have completed the set, they use the answer sheet to check their work.
Students can also complete these problems individually. If they are using this as part of a math center, they can check their own work against the answer sheet. This can also serve as an assessment tool for the standards listed above.
Thanks so much for stopping by. Please let me know if you have any questions. I'd love to hear from you!
