What homework looks like for Sam

  1. 7:04pm

    Homework time. Question 3 is a wall of words.

    Sam has maths homework. He's read question 3 twice and still isn't sure what it's asking. You're making dinner and can't sit with him right now.

    WorksheetQuestion 3 of 8

    A right-angled triangle has two shorter sides of length 3 cm and 4 cm. Using Pythagoras' theorem, calculate the length of the hypotenuse, giving your answer to an appropriate degree of accuracy.

    He snaps the worksheet.

    Sam takes a photo of his homework. Chalk finds the questions on it, and he ticks the one he's stuck on. The rest can wait for another time.

    "Just tell me the answer." Chalk won't.

    Chalk talks him through question 3 out loud and draws the triangle. When he gets tired and asks for the answer, Chalk gives a small hint instead, and a question that gets him moving again.

Questions,
answered

Pick who you are to see the questions people like you ask most.

  1. Chalk is for GCSE learners in England, roughly ages 11 to 16. It was made for children who learn differently, and works for any child who wants patient help.

  2. That's fine. Your child can type everything instead, and everything Chalk says also appears as words on screen.

  3. No. If your child gets something wrong or asks for the answer, Chalk gives a hint or asks a question to help them think.

  4. No. You hold the account and can add up to 3 children. Children under 13 never need their own account.

  5. Chalk is free while we test it, and we don't ask for card details. After that it will be £19.99 a month for the whole family.

  6. Everything your child says or types is checked first. If something worrying comes up, the lesson pauses and your child sees the Childline number. The lesson is flagged in your account, so you can read it and decide what to do next.
