Start hereWords for this lesson

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

WordWhat it meansExample
argumentSpanish: argumento A chain of reasons — equations, drawings, or words — used to defend your thinking. “Two jumbo boxes hold more, because 400 × 2 = 800 > 720.”
conjectureSpanish: conjetura A mathematical statement you believe is true but have not yet proven. “A bigger box ALWAYS holds more cereal” — believed, not yet proven.
counterexampleSpanish: contraejemplo A single example that shows a statement is not always true. One jumbo box sold half full of air breaks “bigger always holds more”.
volumeSpanish: volumen The amount of space a solid figure takes up, measured in cubic units. 8 in × 3 in × 10 in = 240 cubic inches of cereal space.
cubic unitSpanish: unidad cúbica A cube with edges 1 unit long — the unit used to measure volume. One cube, 1 unit on every edge — the block volume is counted in.
patternSpanish: patrón Something that repeats or changes in a predictable way. 1, 3, 7, 15, 31 — each tower's steps follow a predictable jump.

How it worksWorked example

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

Lesson 1.4 — Math is Explaining and Sharing: We can defend a recommendation using equations, drawings, or words — and volume in cubic units gives the equations something exact to say.

  1. Lesson 1.5 — Math is Finding Patterns: We use the patterns and relationships we notice to solve problems, make generalizations, and check that our solutions are reasonable.
  2. Lesson 1.6 — Math is Ours: We make sense of problems, look for patterns, choose representations and tools, make a plan, watch our progress, and shift strategies when needed — together and on our own.

Now you trySame steps, your turn

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

From 1.4: Not every good reason is an equation. Finish this argument: “I recommend buying two jumbo boxes because …”

Answer:

Say it and write itSentence starters

Finish each sentence out loud with a partner. Then use them in your writing.

Watch outA common mistake

Treating 'stuck' as a stop sign instead of a signal — waiting silently instead of trying a strategy: asking a question, drawing the problem, or recalling a similar problem.
