Lesson 17-3 Using Addition to Subtract
Lesson Outline
Gracyn completed a timed math drill in her workbook, “More Minute Math Drills – Addition & Subtraction”. She scored a 100% on her 19 problems of +1 in 1 minute, 25 seconds. She did a great job! Next, we worked on a “Fact Families” worksheet in which Gracyn rolled two dice to acquire the numbers to use in generating the fact family addition and subtraction sentences. In several cases, we added a 10 to the number to increase the difficulty. We are working towards complete independence in Gracyn correctly writing all four sentences. I believe she understands the concept, however at times she mixes the numbers, reads “minus” as “plus”, and needs prompting to remember the steps. When we increased to a 2-digit number, she needed additional help as well. We will continue working with this type of activity in order to increase independence in working with fact families. We worked on Lesson 17-3 from her textbook, “Using Addition to Subtract”. This tasked us with looking at a model with one part pulled out. We then had to find the missing number (other part) to determine its value. The strategy goal in this lesson was to then use more familiar addition facts to find that missing number. We worked through the Guided Practice and Independent Practice as well as the Problem Solving to practice this strategy. In closing, we finished reading the second half of a fun storybook entitled, "If I Were a Plus Sign" by Trisha Speed Shaskan. The book utilized characters in a story format to explain a bit more about addition. Today we read about how a plus sign can add any amount of numbers (and in any order), adding small numbers or big numbers, and finally, that it if we were a plus sign, we could help solve story problems.
