Study Notes

Quarter 1

  • 2-Dimensional Shapes: Identify and compare shapes (triangle, rectangle, square) based on size, orientation, sides, and corners.
  • Numbers up to 100: Count to 100, count up/down from a given number, identify numbers that are 1 more or 1 less than a given number. Represent these numbers using numerals and concrete/pictorial models (e.g., number lines, blocks).
  • Comparing Numbers (up to 20): Compare two numbers up to 20. Order numbers up to 20 from smallest to largest, and vice-versa.
  • Ordinal Numbers (up to 10th): Describe object position using ordinal numbers (1st, 2nd, 3rd, up to 10th).
  • Decomposing Numbers (up to 10): Compose and decompose numbers up to 10 using concrete materials.
  • Addition (up to 20): Illustrate addition of numbers with sums up to 20 using concrete/pictorial models. Illustrate properties of addition (e.g., zero property, commutative property). Solve addition problems.

Quarter 2

  • Measuring with Non-standard Units: Measure length and distance using non-standard units. Compare lengths and distances using non-standard units. Solve length/distance problems with non-standard units.
  • Ordering Numbers (up to 100): Order numbers up to 100 from smallest to largest, vice versa.
  • Place Value (2-digit numbers): Identify place value (tens and ones) in 2-digit numbers, determine value of a digit and identify the digit given its place value. Decompose numbers into tens and ones.
  • Addition (up to 100): Add numbers up to 100 without regrouping, using concrete and pictorial models (2-digit + 1-digit, 2-digit + 2-digit number).
  • Solve problems (oral and pictorial) involving addition (up to 100): Solve addition problems that are given orally or pictorially involving addition.

Quarter 3

  • Operations with 3-4 digit numbers: Solve multi-step problems involving one or more of the four operations (addition, subtraction, multiplication, and division) with results up to 1,000,000.
  • Dividing 3 to 4 digit numbers: Divide 3 to 4-digit numbers by 1-to 2-digit numbers (with and without regrouping) and estimate quotients when dividing by estimating dividends and divisors using multiples of 10.
  • Estimation: Estimate the result of multiplying two numbers where the product is less than 1,000,000.
  • Time Conversions: Convert time units. Convert common units of measurement from larger to smaller units and vice versa (meters and centimeters, kilometers and meters, kilograms and grams, grams and milligrams, liters and milliliters)
  • Fraction Operations: Add and subtract similar fractions with denominators up to 10 using models.
  • Identifying multiples and factors: Identify multiples of given numbers up to 100 and find all the factors of a given number up to 100.

Quarter 4

  • Data Collection and Representation: Collect data with a time element and represent data in tables and single-line graphs. Solve problems that use data generated from two variables.
  • Decimal Numbers: Read, write and determine place value (hundredths) of digits in decimals.
  • Converting between decimals and fractions: Convert decimal numbers to fractions and fractions (with denominators of 10 or 100) to decimals.
  • Decimal Operations: Compare, order, and round decimal numbers to the nearest whole number and nearest tenth.
  • Solving Fraction Problems: Solve multi-step problems involving addition and/or subtraction of fractions..
