Activity: to recognise and represent numbers in order to describe and compare them [lo 1.3.4]
To determine output values for given input values [lo 2.3.2]
1. Do you remember the following? In Grade 5 (Module 2) we looked at the rules for multiplying and dividing by 0 and 1. Let us look at the properties of 0 and 1:
Fill in any number on the left and complete the flow diagram.
1.3
2. Tell a friend which calculations with 0 do NOT change the value of a number.
Note!
Dividing with 0 is not allowed. We say that dividing by 0 is undefined.
3. Once again, fill in numbers on the left and complete the flow diagrams:
3.2
3.3
3.4
4. Tell a friend which calculations with 1 do NOT change the value of a number.
5. Now calculate:
5.1 148 x 0 x 236 =
5.2 0 ¸ 36 =
5.3 34 ¸ 1 x 1 =
5.4 k + 0 =
5.5 c ¸ 0 =
- 58 ¸ 0 =
Assessment
Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.
Assessment Standard 1.3: We know this when the learner recognises and represents the following numbers in order to describe and compare them:
1.3.4: 0 in terms of its additive property.
