Lesson 9: Let’s add multi-digit numbers using column addition
Students will revise and apply column method addition with multi-digit numbers. They will use their knowledge to play a game called Race to the Top.
Lesson 8: Let’s apply subtraction strategies in a game
Students will apply their subtraction strategy skills to play a game called Zero’s Hero.
Lesson 7: Let’s explore subtraction compensation strategy
Students will use their compensation knowledge and apply it to subtraction. They will use their compensation skills to interpret biologists’ observations.
Lesson 6: Let’s use bump strategy subtraction
Students will use bump strategy to subtract while solving subtraction maze puzzles.
Lesson 5: Let’s use jump and split strategy to subtract mentally
Students will apply jump and split strategy skills to subtract mentally. They will use our skills to solve power grid investigation questions.
Lesson 4: Let’s use rounding and mental strategies to problem-solve
Students will use rounding and mental strategies to problem-solve and find the items that each animal purchased.
Lesson 3: Let’s explore compensation strategy
Compensation strategy involves rounding one number to make the number sentence easier to add. The amount rounded is either added or subtracted afterwards to compensate. Students will gain further skills and understanding on number flexibility and how to manipulate numbers to solve problems effectively. They will play a game called Boom Chaka-Laka
Lesson 2: Let’s add using bump strategy
Bump strategy is a strategy that manipulates an addition problem by adjusting one of the amounts to a round number, then doing the opposite to the other number to create an amount equal to the original number sentence. Students will play a game called ‘In the Zone’.
Lesson 11: Let’s apply addition to add 3 multi-digit numbers
Students will use addition strategies to solve challenges and add 3 amounts. This lesson involves problem-solving and critical-thinking skills to complete different challenges.
Lesson 1: Let’s explore mental addition strategies
This lesson explores mental addition strategies that students might already know. Students will specifically explore jump and split strategy addition. They will order ice cream scoops for monsters.
