The Leap to Sixth Grade, a free science course on Tomo

The Leap to Sixth Grade

Bridge the gap between elementary and middle school by mastering the core systems that connect math, science, and history.

Like Duolingo, but for The Leap to Sixth Grade. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through The Logic of Systems and The Story of Societies. It starts from scratch.

What you'll learn

Key ideas in The Leap to Sixth Grade

  • Ratios can compare two independent groups (part-to-part) rather than just a piece of a total
  • The order of numbers in a ratio must match the order of the items being compared
  • A ratio of 3:5 is different from a fraction of 3/5 if the 5 represents a second group rather than the total
  • A unit rate is found by dividing the first quantity by the second to find the value for '1'
  • Comparing different totals is only possible once they are both reduced to a 'per day' or 'per item' basis
  • Distinguishing between part-to-whole fractions and part-to-part ratios
  • Using unit rates to determine the best value or speed
  • Proportions are two ratios that are equal in value
  • Scaling requires multiplying both parts of the ratio by the same factor
  • If you double one side of a relationship, you must double the other to keep it proportional
  • To find the amount for 4 people (double), you must double the flour (6 cups)
  • The relationship between distance and map inches remains constant regardless of the specific numbers used
  • Ratios are the underlying math for 'per' statements
  • Real-world comparisons often involve two different units of measurement
  • Scaling a ratio up or down correctly
  • Applying ratio logic to different real-world scenarios
