Grade 8 Math Curriculum

Activities in the Mathematics grade 8 series cover:

Number Sense & Numeration
  • Review various number systems (whole, integers, fractions & mixed numbers, and decimals) and determining their place value
  • Expressing numbers in a written statement, standard, expanded forms, and scientific notation
  • Comparing and ordering numbers from the various number systems
  • Understanding special number concepts: rounding-off numbers, factors and highest common factors (H.C.F), multiples and lowest common multiples (L.C.M), odd & even number, prime & composite number, composite numbers as products of prime numbers, multiplying and dividing decimals & whole numbers multiples of 10, divisibility by any of the single digit numbers from 1-9, and square roots & perfect squares
  • Four operations (addition, subtraction, multiplication, division) using the various number systems, as well as exponents
  • Order of operations using brackets, exponents, and various numbers systems
  • Review concepts related to percentage; working with percentages
  • Applying percentages to everyday situations (discounts & sales prices, commissions, and loan interests);
  • Review concepts related to ratio, proportion, and rate
  • Metric system units of measure
  • Review the concept of perimeter and how to calculate it- both in questions where all the dimensions  are in the same unit of measurement and in questions where the dimensions are in different units of measurement
  • Review the concept of area and how to calculate it- both in questions where all the dimensions are in the same unit of measurement and in questions where the dimensions are in different units of measurement
  • Calculating the missing dimension of a perimeter, area, and volume measurement questions when given the perimeter, area, or volume and some of the other dimensions
