Lesson PlansCourse: Mastering Skills & Concepts: Course IModule: Addition and SubtractionUnit:SubtractionSession: Differences within 10Learning ObjectivesCounting backwards to find the difference between twonumbers.Recognizing and completing number sentences involvingdifferences within 10.Using subtraction to solve comparison problems within10.OverviewWe're at the bowling alley. We subtract bowling balls from arack. We then compare numbers of pins to find out how manypins a bowler has knocked down.KeywordsMinus (-)SubtractDifferenceTake awayTeaching StrategiesPrior to the sessionHave students discuss the meaning of the words "takeaway", "less", and "compare".Use arrow diagrams to discuss what happens as studentscount backwards from a number.At the end of the sessionHave students use counting-backwards strategies to findthe difference between two numbers, and represent thisusing subtraction sentences.Have students read and write an addition sentence for acorresponding subtraction sentence, e.g. 8 - 3 = 5 and 5 +3 = 8.Give students various number sentences and ask them toconstruct take-away and comparison problems that eachmight represent.© 2001 Riverdeep Interactive Learning Limited.

Wecompare the numbers of red and blue butterflies to find outhow many more red butterflies there are.KeywordsMoreTake awayTeaching StrategiesPrior to the sessionReview the subtraction facts for numbers within 10.Review the concept of one-to-one correspondence tocompare two sets and discuss how the two sets can bemade equal.At the end of the sessionRepresent the number of objects in two unequal sets anduse one-to-one correspondence and subtraction to find thedifference between them.Have students read and write an addition sentence for acorresponding subtraction sentence, e.g. 12 - 7 = 5 and 5+ 7 = 12.Give students various number sentences and ask them toconstruct take-away and comparison problems that eachmight represent.© 2001 Riverdeep Interactive Learning Limited.
