- 2Build a clear visual that supports the numbers in the story
- 3Present findings using accurate vocabulary and short calculations
- 4Reflect on a year of math by celebrating a finished project
Mini Lesson
Today is a celebration. You have spent a whole year using math to solve real problems — counting money, measuring shapes, reading data, writing equations. A showcase is your chance to share one project with an audience: friends, family, neighbors. The goal is not just to show numbers. The goal is to tell a clear story with math behind it.
Three jobs of a math showcase
- Pick a real-world question. A good question is small enough to answer with the math you know — not the whole world, just one slice of it.
- Choose the right tool. Some stories need a chart. Some need a formula. Some need a table or a model. The tool fits the message, not the other way around.
- Communicate findings clearly. Speak in plain words, label every visual, and back every claim with a quick calculation the audience can follow.
Choosing the right tool
- Comparing parts of a whole? Use a pie chart or percentages.
- Comparing several groups side by side? Use a bar chart with clear labels.
- Showing change over time? Use a line graph and mark the axes.
- Predicting future values? Use an equation like y = mx + b and show one sample input.
- Describing a shape, a path, or a region? Use a labeled diagram with units.
Step-by-step: a strong 2-minute presentation
- Open with the question: "How can I save $120 in 6 months?"
- Show the math: $120 / 6 = $20 per month, written as y = 20x.
- Show the visual: a line graph where x = months and y = total saved.
- State one finding: "After 4 months I will have $80."
- Close with a takeaway: why the answer matters or what you would change.
Your project compares 4 favorite foods in your family. Which visual fits best?
Four separate categories side by side is exactly what a bar chart is for. A line graph would imply change over time; a pie chart would only show the share of a single whole, which works too, but a bar chart shows the counts most clearly.
Communicating findings
- Use the math word, not the slang: say "mean" or "average", "perimeter", "equation", "percent of total".
- Round sensibly. $19.99 to the nearest dollar is $20 — fine for a quick claim.
- Show one calculation on a card or slide so the audience can follow your reasoning.
- End with a one-sentence takeaway: "So the bake sale will earn about $70 profit."
A year of G6 math, in five ideas
- Number sense: integers, fractions, decimals, and percent are different costumes for the same value.
- Algebra: an equation is a sentence in math language; you can solve it, graph it, or use it to predict.
- Geometry: shapes and units describe space — area, perimeter, volume, angles.
- Data: charts turn a list of numbers into a picture you can read in seconds.
- Real-world math: budgets, savings, sports stats, and projects are where all of this comes together.
Tip: rehearse once with a timer. Most short presentations go between 90 seconds and 3 minutes. Cut anything that does not help the audience answer the original question.
