Mathematics - Term 1 - Week 10

Problem solving in mathematics involves finding a way to answer a question or solve a challenge. It is important to understand the problem first. We can break down the problem into smaller parts, use drawings or objects to visualize it, and then find a solution step by step. Today, we will practice this by looking at different types of problems and using strategies to solve them.

Let's say you have 3 apples and your friend gives you 2 more. How many apples do you have now? First, we can draw 3 apples and then add 2 more apples. Counting all the apples together, we find that 3 + 2 = 5. So, you have 5 apples in total. This shows how we can use addition to solve a problem.

Now, let's work on this problem together. You have 4 toy cars and you buy 3 more. How many toy cars do you have now? Let's draw 4 toy cars and then add 3 more. Count them together. What do you get? Remember to write down your working: 4 + 3 = ? Let's see how many cars you have in total.

Now it's your turn! Solve these problems on your own. 1) You have 5 balloons, and 2 pop. How many balloons are left? 2) There are 6 birds on a tree, and 3 fly away. How many birds are still on the tree? Write down your answers and show your working clearly. Remember to check your work after you finish!
