Mathematics - Term 2 - Week 8

Problem solving is an essential skill in mathematics. It involves understanding the problem, devising a plan, carrying out the plan, and reviewing the solution. In this lesson, we will explore different strategies to tackle problems, such as drawing pictures, using number lines, and breaking down the problem into smaller parts. We will also discuss the importance of checking our work to ensure accuracy.

Let's say you have 5 apples and you buy 3 more. How many apples do you have now? To solve this, we can use addition. Start with the number of apples you have, which is 5. Then add the 3 apples you bought: 5 + 3 = 8. So, you have 8 apples in total. We can also draw a picture of the apples to visualize the problem.

Imagine you have 12 candies, and you want to share them equally with 3 friends. How many candies does each friend get? Let's solve this together. First, we can divide the total number of candies by the number of friends: 12 ÷ 3 = 4. Each friend gets 4 candies. Now, let's draw a model to show how we divided the candies.

Now it's your turn! Solve the following problems on your own. Remember to show your working clearly. 1. You have 10 marbles, and you lose 2. How many do you have left? 2. There are 8 birds on a tree, and 3 more join them. How many birds are there now? 3. If you read 5 pages of a book each day, how many pages will you read in a week? Write down your answers and be ready to share your strategies.
