Problem solving is an essential skill in mathematics. It involves understanding the problem, devising a plan, carrying out the plan, and reviewing the solution. Today, we will explore different strategies to solve problems, such as drawing pictures, using counters, or writing number sentences. We will also discuss how to check our work and learn from our mistakes.
Let's solve this problem together: 'Lulu has 5 apples and 3 oranges. How many pieces of fruit does she have in total?' First, we identify the numbers involved: 5 apples and 3 oranges. We can use addition to find the total. So, we write the equation: 5 + 3 = 8. Therefore, Lulu has 8 pieces of fruit. We can also draw a picture to visualize the problem, showing 5 apples and 3 oranges together.
Now, let's try another problem together: 'Tom has 7 toy cars, and he gives 2 to his friend. How many toy cars does Tom have left?' Let's break it down. First, we have 7 toy cars. If Tom gives away 2, we need to subtract. We write the equation: 7 - 2 = 5. So, Tom has 5 toy cars left. Can anyone draw a picture to show this? Remember, visual models help us understand the problem better.
Now it's your turn! Solve the following problems on your own. Remember to show your working clearly. 1. Sarah has 10 candies. She eats 3. How many candies does she have left? 2. There are 4 birds on a tree. 2 more birds join them. How many birds are there now? 3. A box has 6 crayons, and you add 4 more. How many crayons are in the box now? Write your answers and be ready to share your strategies with the class.
