For parents: how to use this lesson

You don't need to know this topic yourself. The lesson explains each step on screen, the way Mr Euclid, our Head of Maths, likes it: one tidy step at a time. Every answer is marked straight away with a worked explanation, so you never have to mark anything.

  1. Read what your child will learn together.
  2. Press Start the lesson below and sit with your child for the teaching and the worked examples (about 19 minutes).
  3. Let them do the practice on their own. They choose Getting started, On track or Challenge – start on On track and move up after a few right in a row.
  4. Finish with the exit ticket and the talk question: “Why do we write a zero at the start of the second row?”
  5. Later that day or the next day: the homework (20 minutes), then a practice test.

Watch out for

  • Missing the place-holder zero in the second row. Say "times 30, not times 3" and write the zero before anything else.
  • Mixing up the carried digits from the two rows. Cross out the carries from row 1 before starting row 2.

Miss Hypatia's tip for home: Work out how many hours are in 14 days, or how many minutes are in 24 hours.

What your child will learn

We are learning to multiply by a two-digit number using long multiplication.

Success looks like

  • I can multiply by the ones digit.
  • I can use a place-holder zero for the tens.
  • I can add the rows and check with an estimate.

Key words

long multiplication
a written method for multiplying by a two-digit number
place holder
the zero that shows you are multiplying by tens
partial product
the answer in one row

What to have ready

  • Paper and a pencil
  • This page on a computer, tablet or phone
  • For the hands-on part: Use the grid method on squared paper alongside long multiplication to show where each row comes from. No squared paper? Draw the grid on plain paper.
