Addition within 20
Combine two non-negative whole-number quantities with a total no greater than 20.
Example: 7 + 5 = 12

Choose a general learning context and see a small path into real Sheetroo tools. Coverage is deliberately limited: unreviewed curriculum mappings and missing knowledge are shown honestly, not filled in.

Suggested path
Practise one small set of number facts
Start with addition and subtraction facts within 20, check the preview together, then print only the amount that feels useful.
Next step: Use the default Addition & Subtraction settings first. Visual Arithmetic can add concrete quantity cues, while the Home Revision Pack combines a short family-facing session.
What this knowledge means
Subtraction within 20
Find the difference between two non-negative whole-number quantities without producing negative answers.
Example: 15 − 6 = 9

Suggested path
Prepare matched number-fact practice
Keep one within-20 learning goal while varying support, core and extension practice and retaining matching answers.
Next step: Start in Differentiation Studio, create anonymous variants only when needed, then use an informal exit ticket to check the next teaching step.

Suggested path
Make one routine easier to see and practise
Choose a short, familiar routine and use clear visual steps or calm practice cards without scoring or diagnosing a child.
Next step: Create a Visual Timetable for the real routine. School Readiness Studio offers non-assessment practice, and Matching & Patterns provides a short related table activity.
