Essential Learning Outcomes (ELO)

∎ Students will be able to solve problems involving measurements of liquid volumes and masses of objects. Students will be able to choose the appropriate tools and measure and estimate precisely. (3.MD.2, MP5, MP6 )

Learning targets

• I can estimate with liquid volumes and masses(grams (g), kilograms (kg), and liters (l). (3.MD.2)

• I can measure with liquid volumes and masses (grams (g), kilograms (kg), and liters (l). (3.MD.2)

• I can solve word problems involving masses or volumes given the same units(grams (g), kilograms (kg), and liters (l). (3.MD.2)

• I can use strategies to fluently multiply and divide within 100 (3.OA.7) (Expectation is that by the end of third grade, students know their multiplication and division facts)

Add/Subt within 1000  &  Mult/Div Strategies within 100

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).

Spiral Practice

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.
