Our Current Unit for Grade 5: Multiplication and Division

Our second unit this year is Multiplication and Division.

Multiplication and division facts to 100 (emerging computational fluency)

• Concrete and pictorial representations of multiplication
• Use games to provide opportunities for authentic practice of multiplication computations
• Looking for patterns in numbers, such as in a hundred chart, to further develop understanding of multiplication computation
• Connect multiplication to skip-counting
• Connect multiplication to division and repeated addition
• Using mental math strategies such as doubling and halving, annexing and distributive property
• Focus on recalling facts for 2s, 3s, 4s, 5s, 10s
• Developing computation fluency with facts to 100

(Memorization of facts is not intended at this level)

Multiplication and division to three digits, including division with remainders

• Understanding the relationships between multiplication and division, multiplication and addition, and division and subtraction
• Using flexible computation strategies (decomposing, distributive principle, commutative principle, repeated addition, repeated subtraction)
• Using multiplication and division in real-life contexts and problem-based situations
• Whole class number talks

 Previous Unit: Number Sense – Whole Numbers 

In our first unit of the year students will be focusing on developing their understanding of number sense and whole numbers. The Big Idea from this unit is: Computational fluency and flexibility with numbers extend to operations with larger (multi-digit) numbers. 

Content (What skills we’ll specifically be working on): 

• Number concepts to 1 000 000 

• Counting:  

• Multiples 

• Flexible counting strategies 

• Whole number benchmarks 

• Numbers to 1 000 000 can be arranged and recognized: 

• Comparing and ordering numbers 

• Estimating large quantities 

• Estimation strategies: Front end rounding, compensation, compatible numbers, benchmarks 

• Place value: 

• 100 000s, 10 000s, 1000s, 100s, 10s, and 1s 

• Understanding the relationship between digit places and their value 

• Addition and subtraction of whole numbers to 1 000 000 

• Using flexible computation strategies involving taking apart (e.g., decomposing using friendly numbers and compensating) and combining numbers in a variety of ways, regrouping 

• Estimating sums and differences to 10 000 

• Using addition and subtraction in real-life contexts and problem-based situations 
• Whole-class number talks. 

Grade 4 & 5

Reasoning and analyzing

• Use reasoning to explore and make connections
• Estimate reasonably
• Develop mental math strategies and abilities to make sense of quantities
• Use technology to explore mathematics
• Model mathematics in contextualized experiences

Understanding and solving

• Develop, demonstrate, and apply mathematical understanding through play, inquiry, and problem solving
• Visualize to explore mathematical concepts
• Develop and use multiple strategies to engage in problem solving
• Engage in problem-solving experiences that are connected to place, story, cultural practices, and perspectives relevant to local First Peoples communities, the local community, and other cultures

Communicating and representing

• Communicate mathematical thinking in many ways
• Use mathematical vocabulary and language to contribute to mathematical discussions
• Explain and justify mathematical ideas and decisions
• Represent mathematical ideas in concrete, pictorial, and symbolic forms

Connecting and reflecting

• Reflect on mathematical thinking
• Connect mathematical concepts to each other and to other areas and personal interests
• Incorporate First Peoples worldviews and perspectives to make connections to mathematical concepts
