Teacher Tips

• This continues to build off of the prior measurement question.

• Students will be able to represent whole numbers within 100 on a number line.

• Students can use addition to join lengths and subtraction to compare lengths working within 100.

• Students will now apply their knowledge of measurement to solve word problems using standard units of measure.

• Use MiP Module 2 and Mastering the Basic Math Facts for fact fluency.  Resources here.

• Money   Begin reviewing identifying coins and values before next essential question.  Here is a list of some available resources:   Additional ideas for money

Essential Learning Outcomes (ELO)

∎ Students will make sense of measurement problems and use addition or subtraction equations within 20. (2.MD.A.4)(2.MD.B.5) (2.MD.B.6) (2.OA.B.2)  (SMP 1) (SMP 3)(SMP 4) (SMP 6)   

Learning targets

• • I can measure to figure out how much longer one object is than another. (2.MD.A.4)

  • I can represent whole numbers as lengths on a number line. (2.MD.B.6)

  • I can represent whole numbers  within 100 on a number line. (2.MD.B.6)

• I can use my knowledge of sums and differences to 20 to solve problems using length.(2.OA.B.2)

• I can use the number line to find sums and differences within 20. (2.MD.B.5)

• I can represent addition and subtraction within 100 in an equation to solve measurement word problems.(2.MD.B.5)

Addition & Subtraction Strategies within 20 & 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.

Addition Strategies

Break apart by place value ones more than ten    math flips 2-digit    

Chunking  two-digit & multiples of ten  

Friendly Number   one away   

Compensation    up to 25

Doubles/near  within 20    

Subtraction Strategies

Count up/think addition   up to 50

Word problems are difficult for many students.  The goal is to support students engaging in the context of the problem and going beyond looking for key words and numbers.  Here is a resource that will support applying close reading with math:   Numberless Word Problems                Addition & Subtraction problem types

Interactive manipulatives

“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

Prior knowledge   

Using meters to estimate   Estimating centimeter measures   Estimating measures in meters     Scrabble addition    Making 11

Enrichment

• Inside Mathematics Problem Solving- leveled problems

These are activities to give students mixed, spaced practice based on the big ideas for 2nd grade math.

Data & Graphs  (1st)

• Color Graph

• Pattern Block Graph

Two-step problems   (2nd)

• 2 step word problems

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.
