Grade 9–10 age 14–16

What your child practises here in Grade 9–10, with a real lesson and question from each subject.

Grade 9–⁠10 math here is equations, coordinates, slope and lines. Not here yet: data and statistics, probability, measurement, among others. When your child has learned these, the level moves up. Use it alongside what the school sends home. See the detail

  • A short lesson first
  • Worksheets of 20 to 25 questions, in rounds of 5 or 6
  • Learned means 3 in 4 right, on two different days

Math

Equations with brackets, coordinates, slope and graphing lines, inequalities.

From the lesson · Slope and intercept

Find the slope and the intercept of the line drawn here, and write its equation.

-5-5-4-4-3-3-2-2-1-11122334455
  1. The intercept is the easy one. The line crosses the up-and-down axis at 1, so b = 1.
  2. For the slope, put a finger on that crossing point and move ONE step to the right.
  3. Count how far you must go UP to land back on the line. Three. So the slope is three over one, which is 3.

Answer: y = 3x + 1

English

Advanced vocabulary, word roots, figurative language, tone.

From the lesson · Figurative language

'The city never sleeps' is an example of:

  1. Check whether it is literally true. Cities do not sleep at all, so something figurative is happening.
  2. Look for like or as. Neither is there, so it is not a simile.
  3. Ask what has been handed to the city: sleeping, which only a living thing does.

Answer: personification

AI literacy

Neural networks, how language models work, data and consent.

From the lesson · How language models work

After 'I brushed my', a model gives 'teeth' a 70 per cent chance, 'hair' 25 per cent and 'dog' 5 per cent. What will it most likely write, and could it write something else?

  1. The most likely next token is 'teeth', at 70 per cent.
  2. Models usually pick likely tokens, but not always the very top one.
  3. So 'teeth' is most likely, but 'hair' is quite possible too.

Answer: most likely 'teeth', but it could write 'hair'

What Grade 9–10 AI literacy practises here

  • Neural networksa neural network as layers of simple units that combine their inputs using weights to give an output, and that training adjusts those weights
  • Memorising vs learningoverfitting: a model that memorises its training examples does well on them and badly on new ones, while a model that generalises does well on both
  • How language models worktext split into tokens, a language model choosing each next token from probabilities, why its answer depends on the prompt and on its training data, and why it may play along with a question built on something false or simply agree with you
  • Evaluating a modelusing a simple table of right and wrong predictions to compare models, and choosing the measure that matters for the job rather than accuracy alone
  • Data, consent & privacywhere training data comes from, what consent means, and the rights people have over data about themselves

Not sure Grade 9–10 is right?

Each grade here practises the main topic most schools teach that year. It is not everything your child's school covers. Grades are a guide, not any province's program, so a short warm-up checks your child's level first, in each subject: a child can be in one grade for English and another for math. The level moves up as they learn.
