Lesson 6: Let’s use compensation strategy to add decimals
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. They will use compensation strategy to add decimals and find the winner of the Swim Fest competition.
Lesson 14: Let’s solve place value puzzles
Students will apply their place value knowledge and critical-thinking skills to solve a series of puzzles. This lesson will involve problem-solving, decimal numbers, negative numbers, square numbers and rounding.
Lesson 5: Let’s use split strategy to subtract tenths
Students will apply split strategy to subtract decimals that include tenths while playing a game called Race To Nothing.
Lesson 13: Let’s explore triangular numbers
Students will explore how triangular numbers can be represented in the form of a triangle, with dots or other symbols arranged in a triangular pattern. They will apply this information to answer a series of problem-solving questions.
Lesson 12: Let’s explore negative numbers
Students will introduce the concept that a negative number is any number that is less than zero and explore how they relate to positive numbers. Students will represent negative and positive numbers on a number line while playing a game called Dunk It.
Lesson 4: Let’s use split strategy to add decimals
Students will apply their split strategy knowledge to add decimal amounts and problem-solve. They will use the strategy to help animals choose what to pack based on their suitcase weight limit.
Lesson 11: Let’s explore the order of operations
Students will explore the order of operations using the PEMDAS strategy. The order of operations is applicable to many areas of computation and will be revisited throughout this year. Students will solve puzzles using PEMDAS.
Lesson 3: Let’s apply bump strategy to add and subtract
Students will apply their knowledge of bump strategy addition and subtraction while playing a game called Stock Market Mania.
Lesson 2: Let’s use bump strategy to subtract mentally
Students will apply the skills from the previous lesson to subtract using bump strategy during this lesson. They will complete an activity that involves finding different animals’ power numbers.
Lesson 10: Let’s explore square numbers
Students will explore the concept of square numbers (multiplying a number by itself) and their relation to arrays. They will play a board game, called Square Squared, to practice representing and solving square numbers.
