Step 3: Start lesson 1 and have a look around
This lesson will explore how to add to an amount to create a total that equals the next multiple of ten. This will provide the foundation for bridging to the next ten strategy used in lesson 3.
Bridging to the next ten strategy involves adding a number in parts to another number to get to the next highest ten. This is a helpful strategy that can be applied to more complex problems and used with other strategies.
We will manipulate doubles and ‘near doubles’ (numbers that are very close to each other) in order to develop our flexible-thinking skills.
Jump strategy is a mental math strategy used to manipulate and solve addition problems effectively. Students will break down the smallest 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.
Split strategy involves splitting numbers into each place value amount to create an easier method to mentally add. In this lesson, students will play Split ‘n Sketch, a creative game that involves drawing a chicken.
Students will apply the addition and rounding skills learned in the previous lessons to tackle a problem-solving activity. They will solve clues to find the types of donuts animals have purchased. Students will use the clues to find out the animals’ totals and the type of donuts they bought.
Students will look at the conceptual process of adding like units with place value blocks and visuals. This is the foundation for column addition and understanding regrouping. They will play a game called Space Race.
Students will expand on the previous lesson with the introduction of hundreds and less use of visuals. Students will apply their knowledge of adding using like units to help animals find their hot air balloons.
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.
Students will have an opportunity to apply our column addition knowledge with this problem-solving activity. They will engage in an activity that involves helping dogs match with their bones.
Students will apply a range of addition strategies explored throughout this unit to solve word problems. They will also use REPS strategy to develop a strong approach to effectively solving word problems. They will engage in an activity that involves solving word problems, which match to clues that will expose the ‘Secret Superhero’.
We will use our addition strategies to plan and find the total cost of the ultimate holiday. We could practice different strategies, such as number bonds, bridging to ten, doubles and near doubles, jump strategy, split strategy and column method.
