Count up to find the gap
Explore count-up subtraction with this Grade 2 Glow Math Facts lesson. Connect objects and drawings to equations, explain a strategy, and practice at the learner’s pace.
What children will practice.
Use count-up subtraction to solve subtraction facts and connect objects or drawings to equations.
Facts to explore.
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.
Build it with objects. Draw it. Tell someone how it works.
A problem to explore
A tower is 14 blocks tall and another is 9 blocks tall. How many blocks taller is the first tower?
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.
