Focus on problem types:
Add To- Result Unknown, Take From- Result Unknown, Put Together/Take Apart- Total Unknown, and Put Together/Take Apart- Both Addends Unknown for this essential question (highlighted blue in this doc).
Achieve the Core Progressions documents provide further clarification regarding problem types at different grade levels as follows:
Kindergarten should work with the following four problem subtypes: Add To- Result Unknown, Take From- Result Unknown, Put Together/Take Apart- Total Unknown, and Put Together/Take Apart- Both Addends Unknown
Grade One should work with all problem subtypes. However, the four most difficult problem subtypes are not expected for mastery until Grade 2. These subtypes include Add To- Start Unknown, Take From- Start Unknown, Compare- Bigger Unknown, and Compare- Smaller Unknown
Grade Two should work with all problem subtypes and mastery is expected with all subtypes at this grade level.

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 1st grade math.
students can use geometry vocabulary cards to build shapes using anglegs, geoboards, or other manipulatives
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.
