⭐️ Essential Key Concept ⭐️
B2.1 use the properties of operations, and the relationships between addition, subtraction, multiplication, and division, to solve problems involving whole numbers, including those requiring more than one operation, and check calculations
B2.4 represent and solve problems involving the addition and subtraction of whole numbers that add up to no more than 10 000 and of decimal tenths, using appropriate tools and strategies, including algorithms
E2. Measurement: compare, estimate, and determine measurements in various contexts
E2.3 solve problems involving elapsed time by applying the relationships between different units of time
F1. Money and Finances: demonstrate the knowledge and skills needed to make informed financial decisions
F1.2 estimate and calculate the cost of transactions involving multiple items priced in whole-dollar amounts, not including sales tax, and the amount of change needed when payment is made in cash, using mental math
Related Mathematical Processes: Selecting Tools and Strategies, Reflecting
During this topic, pay attention to the students' ability to maintain positive motivation and perseverance.
Do students have strategies when they are stuck? (e.g. attempt or test out different approaches, use resources in the room, ask for help from a friend)
Are students open to learning from mistakes?
Do students recognize what is working well for them, and what might need to be changed?
