What children will practice.

Use flexible subtraction to solve subtraction facts and connect objects or drawings to equations.

In the learner’s words: I can solve subtraction facts and show why my answer makes sense.

Facts to explore.

16 − 7 = ?12 − 3 = ?18 − 9 = ?14 − 6 = ?

Start with objects or a drawing. Connect the model to an equation, then practice a few facts at a time across two short sessions. Choose a starting point using the learner’s prior instruction.

Let’s work one out · Flexible subtraction
16 − 7=9
For 16 − 7, subtract 6 to reach 10, then subtract 1 to get 9. Check with 9 + 7 = 16.

Build it with objects. Draw it. Tell someone how it works.

A look inside

A problem to explore

A garden has 16 flowers. Seven are picked. How many flowers remain?

An adult may read the problem aloud. Explain your thinking with objects, a drawing, words, or an equation.

From a model to a little discovery.

The complete lesson includes two short teaching sessions, eight practice facts, a story problem, space to show thinking, cut-out fact cards, and a separate answer key for the grown-up.

Use Glow Math Facts as an practice companion. The printable lesson also works away from a screen. Full teaching materials are included with a paid adult account.

Grade 1 introduces models and relationships; Grade 2 revisits strategies and fluency within 20. These are suggested starting points, not learner-placement rules.

Glow’s suggested teaching sequence. Select by prior instruction and readiness; this focused fact-practice collection is not a complete mathematics curriculum or a placement test.
