Need a quick check of addition and subtraction regrouping skills? This 4-question quiz allows students to "show what you know". Two questions are addition and two questions are subtraction. This could be used for small groups, exit slips, or a whole class quick assessment. Students are able to show their work in 2 ways-using the traditional vertical algorithm and/or drawing base-10 blocks (hundreds, tens, and ones). This freebie is a preview of a 3 pack assessment bundle in our store. Happy quizzing!
