Addition by Counting On • Subtraction as the reverse of addition • Subtraction as ‘taking away’ from a set using ‘count back’ strategy Learning Targets • I can add and subtract using part-part-whole concept of number bonds. • I can subtract a part to find the other part. • I can add by using the count-on strategy. • I can subtract a number within 10 by counting back from the number just below the total. • I can make addition and subtraction stories. • I can relate addition and subtraction facts within 10. Learning Tools • Multilink cubes • Addition-fact cards • Subtraction-fact cards • Numeral cards • Word cards • Virtual manipulatives and tools (matholia.com) Suggested Teaching Sequence 1. Use pictorial representations and concrete objects for the number bond concept to introduce and write addition and subtraction equations. 2. Use concrete objects and pictorial representations to reinforce addition using the ‘counting on’ strategy. 3. Use concrete objects and pictorial representations to reinforce subtraction using the ‘crossing out’, ‘counting back’, ‘counting on’ and ‘number bond’ strategies. 4. Write addition and subtraction equations and solve problems individually and in small groups. Group Practice Ideas Work in groups to make addition objects/pictures and write an addition and subtraction equation for each story. Independent Practice Ideas • Addition and Subtraction with number bonds. • Add by count on. • Achieve mastery of basic addition and subtraction facts within 10 . • Subtract using the ‘crossing out’, ‘counting back’, ‘counting on’ and ‘number bond’ strategies. • Write and complete addition and subtraction equations. Review and Assessment Looking Back at the end of the chapter done as a whole group or small group at a center. Ensure students understand and are able to practise adding using number bonds and by counting. Ensure students understand and are able to practise subtraction using the ‘crossing out’, ‘counting back’ and ‘number bond’ strategies. If students have individual access to Matholia, use the review and progress tracking features for summative assessment on this chapter.
