Description
Five self-grading cards for Algebra 1 Keystone Anchor A1.1.1.4.1 - using estimation to solve real-world problems. Students round factors to compatible numbers to estimate products and quotients, use the benchmark fraction one-half to estimate a part of a whole, and estimate a unit rate in miles per gallon. The last card asks students to decide how many tables a school needs and round UP so every student has a seat - a reminder that context, not arithmetic, decides which way you round. Four cards are fill-in-the-blank and one is multiple choice, so students commit to an actual estimate instead of recognizing one. Every card grades itself instantly, and every card carries accessibility text for screen-reader users. Great for Keystone review, bell ringers, test-prep stations, sub plans, or targeted practice on a single anchor. Pairs with the printable five-question assignment for the same standard.
