understanding of the concept of equality, using concrete materials and
addition and subtraction to 10. 




Specific Expectations 




Patterns and Relationships





•identify, describe, and
extend, through investigation, geometric repeating patterns involving one
attribute (e.g., colour, size, shape, thickness, orientation); 




•identify and extend,
through investigation, numeric repeating patterns (e.g., 1, 2, 3, 1, 2, 3, 1,
2, 3, …); 




•describe numeric repeating
patterns in a hundreds chart; 




•identify a rule for a
repeating pattern (e.g., “We’re lining up boy, girl, boy, girl, boy, girl.”); 




•create a repeating pattern
involving one attribute (e.g., colour, size, shape, sound) (Sample problem:
Use beads to make a string that shows a repeating pattern involving one
attribute.); 




• represent a given repeating
pattern in a variety of ways (e.g., pictures, actions, colours, sounds,
numbers, letters) (Sample problem: Make an ABA,ABA,ABA pattern using actions
like clapping or tapping.). 




Expressions and Equality





•create a set in which the
number of objects is greater than, less than, or equal to the number of
objects in a given set; 




•demonstrate examples of
equality, through investigation, using a “balance” model (Sample problem:
Demonstrate, using a pan balance, that a train of 7 attached cubes on one
side balances a train of 3 cubes and a train of 4 cubes on the other side.); 




•determine, through
investigation using a “balance” model and whole numbers to 10, the number of
identical objects that must be added or subtracted to establish equality
(Sample problem: On a pan balance, 5 cubes are placed on the left side and 8
cubes are placed on the right side. How many cubes should you take off the
right side so that both sides balance?).
