Suggested Pacing 3-4 weeks
Continue to build prior knowledge of addition/subtraction strategies by expanding within 1000.
Revisit one digit addition patterns to emphasize addition within tens and hundreds places. For example; 3 tens + 4 tens = 7 tens; 2 hundreds + 6 hundreds = 8 hundreds.

∎ Students will apply properties of operations and their understanding of place value to add and subtract within 1000. (2.NBT.B.7) (2.NBT.B.8) (2.NBT.B.9)(SMP 1) (SMP 2) (SMP 3) (SMP 4) (SMP 5) (SMP 6) (SMP 7) (SMP 8)
I can add and subtract within 1,000 using many strategies. (2.NBT.B.7)
I can solve word problems by using the strategies of adding to, taking from, putting together, taking apart, and comparing. (2.NBT.B.9)
I can solve problems with unknowns in all positions. (2.NBT.B.9)

Choose which strategy students need to practice. You may find that they need many, so start with one for a week or so, then move onto another. You are looking for efficient strategies, not mastery of all strategies. Students may find they prefer one strategy over another or change strategies for different problems. The goal is that they are flexibly using efficient strategies and are able to reason about numbers to fluently compute.

“Closure in a lesson does not mean to pack up and move on. Rather, it is a cognitive activity that helps students focus on what was learned and whether it made sense and had meaning.” How the Brain Learns Mathematics (2007) P. 104
There are many ways to wrap up and reflect the day's activities but this step is often overlooked or rushed. Purposely plan and allow time for students to have closure each day (even if it means setting a timer or daily alarm so you don't run out of time).

These are activities to give students mixed, spaced practice based on the big ideas for 2nd grade math.
These resource sheets are intended to reinforce procedures and concepts. They should not be used as a source of direct instruction or whole-group practice. Please select pages carefully based on your students' needs.
You may have students work on these with a partner, independently with an answer key to self-check (tip: use sheet protectors), or as a journal response. It is not necessary to have students complete a page every day- the intent is to have opportunities to spiral concepts for mixed practice, not do "busy" work.
