Lesson 11: Column method with regrouping
This lesson builds on the previous one, introducing column method with regrouping. Through visual representations, students will develop a strong conceptual understanding of the regrouping process. They will use this knowledge to play a fun spinning wheel game called The Wheel of Nuts.
Lesson 10: Adding like digits up to hundreds
This lesson builds on Lesson 10 by introducing hundreds and transitioning away from visual representations of quantities to working with digits. Students will apply their knowledge of adding using like units to help animals find their hot air balloons.
Lesson 9: Adding like digits
Students will delve into the conceptual process of adding like units using place value blocks and visual representations. This hands-on approach builds a strong foundation for mastering column addition and understanding regrouping. They will then practice adding like units by playing a game called Space Race.
Lesson 8: Using rounding to problem-solve
Students will apply the addition and rounding skills learned in the previous lessons to tackle a problem-solving activity. Students will solve clues to find the types of donuts animals have purchased. They will use the clues to find out the animals’ totals and the type of donuts they bought.
Lesson 7: Explore Split Strategy
Split strategy involves splitting or expanding numbers into each place value amount to create an easier method to mentally add. It is also sometimes referred to as decomposition, partitioning or partial-sums strategy. Students will practice this strategy while playing Split ‘n Sketch, a creative game that involves finding the answers to questions, which will each […]
Lesson 6: Introduction to jump strategy
Jump strategy is a mental strategy used to manipulate and solve addition problems effectively. Students will break down a number into smaller chunks, then add each chunk to the larger number using a number line. This strategy helps provide a strong foundation for mental addition.
Lesson 5: Using doubles and near doubles
Students will manipulate doubles and ‘near doubles’ (numbers that are very close to each other) in order to develop their addition skills and gain more of an understanding of how numbers are flexible. They will practice adding doubles and near doubles by heading to a surf comp to help find each surfer’s score!
Lesson 4: Applying bridging through the next ten strategy
This lesson builds on the previous lesson, focusing on “bridging through the next ten” strategy. By mastering this approach, students will enhance their mental maths skills and strengthen their overall number sense. Students will practice their mental math skills by helping the animals figure out the total cost of the purchases after a day at […]
Lesson 3: Introduction to bridging through the next ten strategy
“Bridging through the next ten” is a strategy that builds upon the knowledge students gained in Lesson 2; finding the next multiple of ten. Bridging through the next ten involves adding a number in parts to another number to get to the next multiple of ten, then adding the remaining amount. This is a helpful […]
Lesson 2: Finding the next multiple of ten
Students will explore how to add specific amounts to reach the next multiple of ten. This activity lays the groundwork for the “bridging to the next ten” strategy, which will be further developed in lessons 3 and 4. They will practice this strategy by creating number trees.
