Our Current Unit for Grade 5: Fractions and Decimals

Big Idea: Numbers describe quantities that can be represented by equivalent fractions.

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

• decimals to thousandths
• equivalent fractions
• whole-number, fraction, and decimal benchmarks
  • Two equivalent fractions are two ways to represent the same amount (having the same whole).
  • comparing and ordering of fractions and decimals
  • addition and subtraction of decimals to thousandths
  • estimating decimal sums and differences
  • estimating fractions with benchmarks (e.g., zero, half, whole)
  • equal partitioning

• addition and subtraction of decimals to thousandths

• • estimating decimal sums and differences
  • using visual models such as base 10 blocks, place-value mats, grid paper, and number lines
  • using addition and subtraction in real-life contexts and problem-based situations
  • whole-class number talks

Ways to support your child at home:

• Noticing where fractions and decimals are used
• Making connections to fractions and how they are used in daily life for cooking and baking.
• Making connections to decimals and how they are used in daily life for money.
• Practicing making equivalent fractions and decimals
• Playing Fraction War at home
• Completing the Boddle assignment on fractions

Previous Unit: Measurement – Area & Perimeter

Big idea: Closed shapes have area and perimeter that can be described, measured, and compared.

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

• units of measure (mm, cm, m, km)
  • relationship between them
  • converting between different units of measure
• area measurement of squares and rectangles
• relationship between area and perimeter
  • measuring area of squares and rectangles, using tiles, geoboards, grid paper
  • investigating perimeter and area and how they are related to but not dependent on each other

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
