In this whopping 234 page packet, prep is simple - print, cut in half (laminate if desired) and it's ready to use and really that simple.
The students solve addition problems for all possible combinations from 1-20. They match their addition card to the corresponding correct Base 10 illustrated answer card.
This packet is large enough for everyone in class to work on it at the same time for whole group practice, or during independent Center Time time as a math skills game, or intervention, differentiation, assessment or extension between home and school.
Please note: I have included ALL possible addition combinations for each number. As well as created them to "switch positions" to foster the understanding that they will equal the same result.
This is an excellent way to assess if your students have mastered addition of facts 1-20 and is Common Core Aligned.
