Notes

Day 4: Teacher-Made Lesson

Warm Up

Warm-up/Launch: (or do a ‘ways to make X” as a quick warm-up?)

● Do string from CFLM Measuring for the Art Show unit’s Day 7 (p 37)….but adapt string to the following:
31 + 10
31 + 11 <--adding in these first two helper problems --see note about this below
26 + 10
26 + 12
26 + 22
44+30 (probably stop here due to time?)
44+39
57+39

Teacher NOTE: *I feel like I always love the first two problems (26 + 10, 26 + 12) but then always want to ‘try that again’ before changing something in the tens place (26 + 22). Therefore I’m going to add in the first two problems for additional practice with just changing the ones place.
● discuss just drawing a line to represent the measuring strip
● highlight when students used what they already did to help them
● Begin ‘Helpful Addition and Subtraction Strategies' Chart: “Use what you already know to help you”

Launch

(Because the string will take longer today, it is the warm-up/launch for today. See above.)

Workshop

● Use "keep one number whole" practice problems

*teach/model the structure of rallycoach (IF PREVIOUSLY KAGAN TRAINED- OTHERWISE DO AS REGULAR PARTNER WORK and encourage behaviors from Unit 1's "working together" chart!!!!)
-give one paper, one pencil to heteorgeneous partners with more than enough problems on it (have HIGHER student be the ‘player’ first so the lower student can ‘coach’ aka have another opportunity to see it done successfully)
● encourage them to apply what we did in strings to help them today
● teacher walk-around and note students’ levels, conference/support
● do a mid-workshop congress if necessary

Congress

● highlight pairs who demonstrated habits of good mathematicians/using the structure rally coach successfully/demonstrating 'working together' habits from Unit 1
● discuss the strategies students used- highlight kids who decomposed the smaller number and used +10 to help them

BEGIN ADDITION STRATEGIES CHART if haven't already done so and record this strategy!
