Illustrative Mathematics K–5 · Grade 3 · Unit 8 · Putting It All Together
It’s Field Day, the last big day of the year! Guess fractions at the Guessing Booth, run the Fraction Relay, plan floors at the Tiny House Lot, shop at the Tiny House Shop, read graphs at the Survey Tent, and play with facts on Game Day. Then win ribbons on the Victory Lap. Each station reviews lessons from class.
Each station deals 8 fresh problems (the Victory Lap deals 10). A right answer on the first try earns 10 points. After a wrong answer, the game names the likely mistake and gives one more try for 5 points. On the Victory Lap, each right answer wins a ribbon.
Hints use the pictures from the year: strips and number lines cut into equal parts, jumps along a fraction number line, floor plans with each room’s multiplication, and bar graphs with the bars to compare outlined. A used hint caps that problem at 5 points.
Estimates too big or too small, counting the tick at 0, using the whole number line for the bottom number, mixing up area and perimeter, adding side lengths for the area, finding one room or one floor when the question asks about more, forgetting to regroup, taking only one price from the budget, adding where a story multiplies or divides, counting spaces on a bar graph instead of reading the scale, and comparing with only one bar in a two-step question.
Fractions have denominators 2, 3, 4, 6, and 8, up to 3 wholes. Tiny houses use the sizes from class: a shipping container 8 feet by 20, a school bus 7 by 14, and a cabin 8 by 10 with a loft. Multiplying stays within 100, or a one-digit number times a multiple of 10. Prices add to $1,000 or less, regrouping at most once in a place. Bar graphs have a line every 2, 5, or 10.
Each station matches a chapter of the Learn page for this unit, which reviews the ideas step by step.
Taking a survey (Lesson 6) is done with a class, so the Survey Tent starts from survey results. Designing your own tiny house (Lesson 4) is open-ended, so the game gives the floor plans. Lessons 12 to 15 (Notice and Wonder, How Many Do You See?, Estimation Exploration, and Number Talk) are talks best done with others, so there are no stations for them.
