These exercises and activities are for students to use independently of the teacher to practice number properties.
Number Framework domain and stage:
Fractions, stages 4 - 5, advanced counting to early additive part-whole
Number, level 3
Numeracy Project book reference:
These activities can be used to follow the teaching episodes based on, Book 7, page 9 and are for those students who are able to use the associated number properties.
Prior knowledge. Students should be able to:
- Sharing by dealing
- Recall basic addition facts, including doubles knowledge. For example, 50 + 50 = 100, 3 + 3 + 3 = 9
During these activities, students will meet:
- Dividing by sharing into equal sets (equal subtractions)
Halving as the opposite of doubling may be a worthwhile piece of learning that can develop from discussions around the answers to exercise 3, where students are just halving numbers.
Remember that students who have not reached stage 6 in the "basic facts" domain have not learned all of their basic multiplication facts, so a multiplicative strategy based purely on the numbers may not work for all students.
