Money - Adding money in different denominations up to Sh.1000 (2)

By the end of the lesson, the learner should be able to:

- Add money in different denominations with regrouping
- Solve real-life problems involving addition of money
- Show interest in adding money

- Learners in groups practice adding money with regrouping from cents to shillings
- Learners solve addition problems involving money in real-life situations
- Learners use a price list to calculate the total cost of multiple items

Position and Direction - Identifying right and left side from a point
Shapes - Identifying shapes in a combined shape made of two different shapes

By the end of the lesson, the learner should be able to:

- Identify the right side from a point
- Identify the left side from a point
- Appreciate the use of right and left directions in daily life

- Learners in turns identify objects that are on their left side
- Learners in turns identify objects that are on their right side
- Learners describe the position of objects using 'to the right of' and 'to the left of'
- Learners play games involving identification of right and left sides

How can you identify if an object is to your right or left?
