Math Games

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

Translate repeating patterns from one representation to another.

Describe equality as a balance and inequality as an imbalance, concretely and pictorially (0 to 20).

Record equalities using the equal symbol.

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.

Sort 3-D objects and 2-D shapes using one attribute, and explain the sorting rule.

Replicate composite 2-D shapes and 3-D objects.

Compare 2-D shapes to parts of 3-D objects in the environment.

Say the number sequence, 0 to 100, by:
• 1s forward and backward between any two given numbers
• 2s to 20, forward starting at 0
• 5s and 10s to 100, forward starting at 0.

Describe and use mental mathematics strategies (memorization not intended), such as:
• counting on and counting back
• making 10
• doubles
• using addition to subtract to determine the basic addition facts to 18 and related subtraction facts.

Recognize, at a glance, and name familiar arrangements of 1 to 10 objects or dots.

Demonstrate an understanding of counting by:
• indicating that the last number said identifies “how many”
• showing that any set has only one count
• using the counting on strategy
• using parts or equal groups to count sets.

Represent and describe numbers to 20 concretely, pictorially and symbolically.

Compare sets containing up to 20 elements to solve problems using:
• referents
• one-to-one correspondence.

Estimate quantities to 20 by using referents.

Demonstrate, concretely and pictorially, how a given number can be represented by a variety of equal groups with and without singles.

Identify the number, up to 20, that is one more, two more, one less and two less than a given number.

Demonstrate an understanding of addition of numbers with answers to 20 and their corresponding subtraction facts, concretely, pictorially and symbolically by:
• using familiar and mathematical language to describe additive and subtractive actions from their experience
• creating and solving problems in context that involve addition and subtraction
• modeling addition and subtraction using a variety of concrete and visual representations, and recording the process symbolically.
