    • 1.PR.1
      Demonstrate an understanding of repeating patterns (two to four elements) by:
      • describing
      • reproducing
      • extending
      • creating
      patterns using manipulatives, diagrams, sounds and actions.

      • Achievement Indicators:
      - 1PR1.1 Describe a given repeating pattern containing two to four elements in its core.
      - 1PR1.2 Identify and describe errors in a given repeating pattern.
      - 1PR1.3 Identify and describe the missing element(s) in a given repeating pattern.
      - 1PR1.4 Reproduce and extend a given repeating pattern using manipulatives, diagrams, sounds and actions.
      - 1PR1.5 Identify and describe, using every day language, a repeating pattern in the environment, e.g., in the classroom, outdoors.
      - 1PR1.6 Identify repeating events; e.g., days of the week, birthdays, seasons
      - 1PR1.7 Create and describe a repeating pattern, using a variety of manipulatives, diagrams, sounds and actions.
    • 1.PR.2
      Translate repeating patterns from one representation to another.
      • Achievement Indicators:
      - 1PR2.1 Represent a given repeating pattern, using another mode; e.g., actions to sound, colour to shape, ABC ABC to moose, puffin, bear, moose, puffin, bear.
      - 1PR2.2 Describe a given repeating pattern, using a letter code; e.g., ABC ABC,…
    • 1.PR.3
      Describe equality as a balance and inequality as an imbalance, concretely and pictorially (0 to 20).
      • Achievement Indicators:
      - 1PR3.1 Construct two equal sets, using the same objects (same shape and mass), and demonstrate their equality of number, using a balance scale.
      - 1PR3.2 Construct two unequal sets, using the same objects (same shape and mass), and demonstrate their inequality of number, using a balance scale.
      - 1PR3.3 Determine if two given concrete sets are equal or unequal, and explain the process used.
    • 1.PR.4
      Record equalities using the equal symbol (0 to 20).

      • Achievement Indicators:
      - 1PR4.1 Represent a given equality, using manipulatives or pictures.
      - 1PR4.2 Represent a given pictorial or concrete equality in symbolic form.
      - 1PR4.3 Provide examples of equalities where the given sum or difference is on either the left or right side of the equal symbol (=).
      - 1PR4.4 Record different representations of the same quantity (0 to 20) as equalities.

    • 1.SS.1
      Demonstrate an understanding of measurement as a process of comparing by:
      • identifying attributes that can be compared
      • ordering objects
      • making statements of comparison
      • filling, covering or matching.

      • Achievement Indicators:
      - 1SS1.1 Identify common attributes, such as length, height, mass, capacity and area, that could be used to compare two given objects.
      - 1SS1.2 Order a set of objects by length, height, mass, capacity or area, and explain their ordering.
      - 1SS1.3 Compare two given objects, and identify the attributes used to compare.
      - 1SS1.4 Determine which of two or more objects is longest or shortest by matching, and explain the reasoning.
      - 1SS1.5 Determine which of two or more objects has the greatest or least area by covering, and explain the reasoning.
      - 1SS1.6 Determine which of two or more objects holds the most or least by filling, and explain the reasoning.
      - 1SS1.7 Determine which of two or more objects is heaviest or lightest by comparing, and explain the reasoning.
    • 1.SS.2
      Sort 3-D objects and 2-D shapes, using one attribute, and explain the sorting rule.
      • Achievement Indicators:
      - 1SS2.1 Sort a set of familiar 3-D objects or 2-D shapes, using a given sorting rule.
      - 1SS2.2 Sort a set of familiar 3-D objects using a single attribute, determined by the student, and explain the sorting rule.
      - 1SS2.3 Sort a set of 2-D shapes using a single attribute, determined by the student, and explain the sorting rule.
      - 1SS2.4 Determine the difference between two pre-sorted sets of familiar 3-D objects or 2-D shapes, and explain a possible sorting rule used to sort them.
    • 1.SS.3
      Replicate composite 2-D shapes and 3-D objects.
      • Achievement Indicators:
      - 1SS3.1 Select 2-D shapes from a set to reproduce a composite 2-D shape.
      - 1SS3.2 Select 3-D objects from a set to reproduce a composite 3-D object.
      - 1SS3.3 Predict and select the 2-D shapes used to produce a composite 2-D shape, and verify by deconstructing the composite shape.
      - 1SS3.4 Predict and select the 3-D objects used to produce a composite 3-D object, and verify by deconstructing the composite object.
    • 1.SS.4
