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