2.OA.2 - Fluently add and subtract within 20 using mental strategies. By the end of grade 2, know from memory all sums of two one-digit numbers.
This packet is a painless way to get started with the math Common Core State Standard 2.OA.2. It will help you make informed decisions on how to best teach the concept of using mental strategies to add and subtract within 20. Classroom activities and student learning targets are suggested. A short assessment that can easily be used as a pre-assessment as well as a post-assessment is part of the package too!
Finally the journal prompts, which come in three different formats, can be used as learning tools in students’ journals or as an exit slip to equip you with valuable formative assessment data. Journal prompts can be used in a Daily 5 Math center.
Check out the MANY other guides we have available as well as the center games we have listed.
