Why This Matters Missed a lesson — or just want a refresher? This catch-up station reviews Lessons 1.1–1.3: 1.1 Math is Mine, 1.2 Math is Exploring and Thinking, 1.3 Math is In My World. Work one example from each lesson, then prove you're caught up in the mixed practice.

Start hereWords for this lesson

Read each word before you begin. Say it out loud.

WordWhat it meansExample
doer of mathSpanish: persona que hace matemáticas Anyone who uses mathematical thinking — which is everyone, every day. Splitting a bill 4 ways at dinner — that is a doer of math.
math storySpanish: historia matemática Your own history with mathematics — what you have done, felt, and learned so far. “In 3rd grade I hated fractions; this year I can explain them.”
strengthSpanish: fortaleza Something you already do well and can share with others. “I am good at mental math with money” — a strength you can teach.
decomposeSpanish: descomponer To break a number into parts that add, subtract, multiply, or divide back to it. 78.5 = 70 + 8.5, and also 157 ÷ 2 — both rebuild the same number.
estimateSpanish: estimar A reasoned answer that is close enough to be useful, without counting every one. 20 cars × about 4 riders ≈ 80 people on the Ferris wheel.
quantitySpanish: cantidad An amount in a problem — a number with a meaning attached, like 540 meters. 540 meters — the number 540 AND what it measures.

How it worksWorked example

These numbers are not on your problems. The steps are. Follow them with your own numbers.

A Ferris wheel has 20 cars. About 4 people fit in each car. About how many people can ride at one time?

  1. Count the equal groups: 20 cars
  2. Estimate the size of one group: about 4 people
  3. Multiply the groups by the group size: 20 × 4 = 80
  4. About 80 people can ride at one time.
  5. One small group of peas has about 10 peas. About 12 groups like it fill the bowl. About how many peas are in the bowl?
  6. Count one small group: about 10 peas
  7. Count how many groups fill the bowl: about 12 groups
  8. Multiply the groups by the group size: 12 × 10 = 120
  9. About 120 peas are in the bowl.
  10. One tram ride takes 12.5 minutes. How many minutes do 50 rides take?
  11. Write one ride in the table: 1 → 12.5
  12. Find the time for 10 rides: 12.5 × 10 = 125
  13. Multiply by 5 to get 50 rides: 125 × 5 = 625
  14. 50 rides take 625 minutes.

Now you trySame steps, your turn

The steps are the same as the worked example. The numbers are yours. Do the work.

A parking lot has 10 rows. About 9 cars fit in each row. About how many cars fit in the lot?
