Lesson walkthrough

Build an Addition Fact

Count each group. Then count all the objects to find the sum.

Visual on the sheet: AdditionModel showing 7 + 5 = 12, drawn as an exact vector diagram.

Use a Number Line

Begin at the first marked number. Follow the jump to the ending number. Explain whether the jump shows addition or subtraction.

Practice Subtraction

Start with the whole group. Cross out the removed objects. Count what remains to find the difference.

Visual on the sheet: SubtractionModel showing 16 − 7 = 9, drawn as an exact vector diagram.

Think in Tens and Ones

Study the place-value blocks. Count the tens, count the ones, and name the number shown.

How to use this sheet

Print the sheet on US Letter paper or project it for whole-class instruction. Work the walkthrough sections in order, pause at each visual to have students describe what they see, then use the check-for-understanding prompts as an exit ticket. The vocabulary block doubles as a word wall, and the worked examples can be re-lettered for homework or centers.
