Step 3: Start lesson 1 and have a look around
Students will explore how to add and subtract 1, 10 and 100 using place value knowledge and number patterns. They will develop a strong understanding of how each digit changes, building fluency and number sense.
Students will use the counting-on strategy to approach subtraction, where they start from the smaller number and count on to reach the larger number. This method helps students to build a deeper understanding of subtraction and develop stronger number sense. Students will play Strategic Subtraction, a fun card flipping game.
This lesson reviews the “bridging to the next 10” strategy for addition and introduces its application in subtraction. Students will learn how to use this strategy to make subtraction more efficient and develop a deeper understanding of number relationships. The will use a game, called Risk It For The Biscuit, to consolidate their learning.
This lesson will explore the relationships between numbers and how understanding these patterns can empower students to subtract with greater efficiency. They will ‘go shopping’ to practice their skills.
Students will delve into the relationship between addition and subtraction through inverse operations and related facts, highlighting how addition can be effectively used to solve subtraction problems. They will build fact family houses using picture prompts.
Students will be asked to investigate how they could use their knowledge of jump and split strategy and apply it to subtraction. They will then have the opportunity to refine and apply this strategy with a problem-solving activity that involves finding the missing amounts from each animal’s story.
Students will explore jump and split strategy to solve subtraction problems, building on their understanding and enhancing their subtraction skills. They will apply their skills to help customers calculate change at a yard sale.
Students will explore how to use column method to subtract. They will gain a conceptual understanding on how to regroup from larger place values through concrete and pictorial examples. They will use their knowledge to find the amount of treasure each pirate ship has lost.
Students will apply column method to subtract, strengthening their ability to solve problems with greater accuracy and efficiency. They will utilise their skills to play a subtraction bingo game.
Students will use flexible thinking to manipulate numbers and subtract larger numbers effectively. They will use their knowledge and skills to help animals choose books to purchase.
Students will consolidate and apply a range of addition and subtraction strategies to problem-solve, such as counting on, bridging down to ten, jump strategy, split strategy and column method. They will utilise these strategies in a critical-thinking activity that involves finding the ages of members of an animal family.
