The purpose for this question is to lay foundational skills for third grade multiplication.
This is an opportunity to transfer the partitioning of rectangles into building arrays.
Have students write expressions to represent the arrays.
Emphasize repeated addition as well as relate this to skip counting concepts.
This is the time to revisit odd and even.

⊡Students will gain foundations for multiplication by working with equal groups of objects by looking for and making use of structure including odd and even groupings.
I can determine whether a group of objects has an odd or even number of members. (2.OA.C.3)
I can write an equation to express an even number as a sum of two equal addends. (2.OA.C.3)

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 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.
