I used this powerpoint as a basic review that covers all 4.NBT (A and B) CCSS. There are 32 questions, and students will answer each question on whiteboards.
There is a task card version of this resource. Check it out here!
Students will review reading and writing whole numbers, recognizing the value of digits (ones-millions), writing numbers in standard, expanded, and word form, rounding, and performing all four operations with whole numbers.
Could be used as a pre-assessment to the unit, exit tickets throughout the unit, or a review at the end of the unit. Make it a competition between table groups! Enjoy!
