Teacher Tips
The new concept for area is irregular figures and missing side lengths
Students will need to multiply up to a 4 by 1 and 2 by 2.
Lattice multiplication is not a place value strategy and should NOT be used to teach multi-digit multiplication.
Students use knowledge of repeated addition to multiply multi-digit numbers.
∎Students will reason abstractly and quantitatively while using place value understanding and properties of operations to perform whole number multi-digit arithmetic. 4.NBT.5
⊡ Students will connect and apply area and perimeter formulas to calculate perimeter and area of a shape in real life problems. 4.MD.3 SMP.2 SMP.3 SMP.4 SMP.5 SMP.6 SMP.7
I can use the formula for the area of a rectangle, a=(lxw) to solve real world and mathematical problems. 4.MD.A.3
I can use the area formula to solve problems including unknown length or width problems. 4.MD.A.3
I can use the perimeter formula to solve problems including unknown lengths or width problems. 4.MD.A.3
I can multiply a four digit by one digit, or two digit by two digit numbers using an appropriate strategy. 4.NBT.B.5

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).
Ideas for closure activities
These are activities to give students mixed, spaced practice based on the big ideas for 4th 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.
