Addition of numbers

Numbers should be arranged correctly according to their place value. When adding we start from ones. If there is any carrying, then we carry 1 ten to tens.

We continue in that order until all numbers are added correctly.

Activity

1. Primary School Mathematics bk 3 pg 14.
2. Understanding MTC bk 3 pg 12

Therefore, the same will be done towards word sums.

Activity:

1. Primary Mathematics Bk 3 pg 11.
2. Primary MTC for Uganda bk 3 pg 25, 26
3. Mk mathematics book three page 44 and 46

Subtraction of members with regrouping and without regrouping

Numbers should be arranged correctly according to their place value. When subtracting we begin with or start handling with one. If there is borrowing (re-grouping). It is done in groups of tens.

That order is done until all numbers are completed.

Example

Activity:

Mk mathematics book three pages 48, 50 and 52

Word sums involving subtractions

The same will be done in handling word sums

Activity:

1. Mk Primary Mathematics book 3 pages49, 51and 54.
2. Understanding mathematics pg 21 – 24, 44.

Multiplying two digits by two.

Example; 1

12 x 13

12

x     13

36

+ 120

156

Example 2

12 x 13                    Expand 12               10 + 2

10 x 13 = 130

2 x 13 = + 26

156
