Douglas Clements' Learning Trajectories have been linked to the Ontario Math Expectations for Grades K through 3.
Assessments in math have been made easier with this resource. It takes the guess work out of determining students strengths, needs and next steps. It allows you to see where a student is developmentally and where he/she should be according to curriculum expectations.
Print this resource back to back so you can see both the trajectories and expectations at a glance.
