Problem solving in mathematics involves identifying a problem, devising a plan, carrying out the plan, and reviewing the solution. This week, we will focus on using different strategies such as drawing diagrams, using number lines, and breaking down problems into smaller parts. These strategies help us visualize the problem and find the best solution.
Suppose you have 3 apples and your friend gives you 5 more. To find the total number of apples, we can use addition. The equation is 3 + 5 = 8. We can also draw a picture of 3 apples and then add 5 more to see that we have a total of 8 apples. This visual representation helps confirm our answer.
Imagine you have 12 candies, and you want to share them equally with 3 friends. How many candies will each friend get? Let's work through this together. First, we can divide 12 by 3. Using a number line, we can count how many groups of 3 fit into 12. Each friend will receive 4 candies. Let's discuss how we arrived at this answer and any other methods we could use.
Now it's your turn! Solve the following problems on your own. Remember to show your working clearly. 1) If you have 15 marbles and you lose 7, how many do you have left? 2) A book costs R45, and you buy 3 books. How much do you spend in total? 3) You have 20 stickers, and you give 5 to each of your 4 friends. How many stickers do you have left? Write down your answers and be ready to discuss your strategies.
