Lesson 14: Let’s show what we know!
Students will show their knowledge of all the key ideas from this subtraction unit. Please note, you can either complete an onscreen assessment or a printed version of the assessment.
Lesson 13: Let’s apply subtraction strategies to problem-solve
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.
Lesson 12: Let’s use flexible numbers and regrouping
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.
Lesson 11: Let’s solve word problems
Students will use their addition and subtraction skills and REPS strategy to solve word problems.
Lesson 10: Let’s subtract up to 3-digit numbers
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.
Lesson 9: Let’s use column method to subtract
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.
Lesson 8: Let’s apply split/jump strategy to subtract
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.
Lesson 7: Let’s use jump and split strategy to subtract
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.
Lesson 6: Let’s explore related facts
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.
Lesson 5: Let’s use patterns to subtract
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.
