Grade Level:

Subject:
Math
Topic:
Adding Three-Digit Numbers Using Place Value / Mental Math
Objective:
Students will use strategies to apply mental computation by building on number relationships to solve problems and avoid relying on memorization procedures.
Other Information:
The information was gleaned from a recent formative quiz adding three-digit numbers using the expanded form to solve. We had a twenty minute lesson before lunch which reviewed equations with sums to 1,000. Then, right before lunch, Kiley presented one that required extra time.
The quiz showed all but one student missed 681 + 502 = _____.

Reflection:
I discovered many of the students did not want to show their work. Those who didn't had the most errors. I also discovered that some solved in unique ways, but their way was accurate, so it was allowed. Information Kristina brought back from a recent Math Cadre Training said the students may choose how to solve, so I'm allowing it if there is evidence of understanding backed by high scores. She also shared the need to move away from concrete to abstract which I believe is required to develop fluency for those who are ready. More are embracing the mental math as they form picture connections in their heads and grow in understanding of place value. I continue to see a split in abilities and struggle to meet all the needs. I need to move those who have mastered this to the subtraction phase and continue to scaffold the ones who have not mastered these skills by reteaching them in small groups.
