Rename fractions to a common denominator, then add or subtract them like the ingredients they are. Mixed numbers, regrouping, and estimation all included.
Plot ordered pairs on a first-quadrant grid to trace a treasure route, then sort quadrilaterals into a family tree where properties flow from parent to child.
Split a garden into fractional plots and watch what happens when you take a fraction of a fraction, scale an area, or share a unit fraction among neighbors.
Feed numbers into a chain of pattern machines. Rules like +3 and ×2 make sequences; a coordinate plane plots the pairs so the pattern is visible at once.
Stack, add, and multiply prices at a virtual market. Line up decimal points, use an area model for multi-digit products, and estimate before you calculate.
