Texas Essential Knowledge and Skills for Mathematics

Teacher's field guide

What Students Need to Do: Students decide whether to use money for something now or keep it for something later. They explain how each choice affects what they can buy.
What Mastery Looks Like: A student can identify the choice between buying an item now and keeping money for a later goal. The student can explain what is gained and given up with each choice.
Common Misconceptions: Some students think keeping money means never using it, rather than waiting for a later goal. Others think they can buy something now and still have the full amount later.
How to Assess It: Exit ticket: Maya has $8. She can buy a $6 toy today or keep the $8 toward a $12 game. Ask students to name both choices and explain what happens with each.

Lesson moves

Give pairs 20 play dollars, item cards, and a savings jar, then have them choose purchases while reserving money for a goal.
Ask, “Would you buy a $5 toy now or keep the money for a $10 book later, and why?”
Play Goal or Buy: students draw choice cards and explain whether each choice helps them reach a pictured savings goal.
Compare a class snack purchase with keeping the same amount for a future field trip, using a simple two-column chart.
