Learning focus
Skills this problem practices
What a successful response demonstrates, with each skill’s share of the content rating.
Double and halve whole-number quantities
The learner can double and halve whole-number quantities. The capability is credited only when the task makes that demand necessary for success.
Readiness
Helpful prerequisites
Skills the rating assumes are already available to the learner.
Solve one- and two-step addition/subtraction stories within 100
The learner can solve one- and two-step addition/subtraction stories within 100. This capability is distinct from mere exposure to or isolated use of Grade 1 story structures.
