Addition & subtraction to 20 at Year 1: what the curriculum expects

Year 1 addition and subtraction covers combining and separating collections, number bonds to ten and twenty, counting on and counting back, doubles and near doubles, and simple worded problems. The Victorian Curriculum wants children to use a strategy and to read the equals sign as meaning the same as.

This topic sits inside the Victorian Curriculum for Year 1 maths; the questions stay at the easy and at-level tiers so the result is a fair check of the foundations.

Common addition and subtraction to 20 misconceptions tutors see

The distractors in this quiz are built from real misconceptions rather than random wrong numbers, so a specific wrong answer usually points to a specific gap. The ones we see most at Year 1:

Each of these is fixable in a session or two once it has been named, which is why the results panel below shows the correct answer and an explanation rather than just a score.

Practising addition and subtraction to 20 with a Year 1 student

The habits that move addition and subtraction to 20 from shaky to secure at Year 1:

  1. Use a ten-frame to make the bonds to ten visible, then extend to twenty.
  2. Roll two dice and add them; roll one and subtract it from ten.
  3. Turn everyday events into number stories: we had 12 grapes and ate 5.

At this age, ten minutes of playful, concrete practice beats a worksheet. Use real objects, talk through what is happening and stop while it is still fun.

How the 10 questions are chosen

The 10 questions are drawn from 10 eligible items on addition and subtraction to 20 in our Year 1 maths bank, including some stretch-tier questions so there are enough to make a full set. The selection is fixed for this address so a shared link shows the same quiz; press New set of questions or add ?seed= to the address for a different mix. Options are shuffled, no two questions share a stem, and the answer key is fetched from our server only after you submit, so it is not hidden in the page.

A single-topic quiz is more precise than a mixed one: if the score here is low, the gap is in addition and subtraction to 20, not somewhere in Year 1 maths generally. It is still short, though, and it cannot show how a student copes with the stretch and challenge questions that decide a top result. That is what the free Skills Check adds.

How to read a score out of 10

9 or 10 out of 10
The easy and at-level content is secure. The useful question now is how far above the year level the student can go, which a ten-item quiz cannot show. The free Skills Check adds stretch and challenge questions on every topic so you can see the ceiling as well as the floor.
7 or 8 out of 10
Solid, with one or two specific gaps. Look at which topic the incorrect answers came from (the results panel names the weakest topic) and spend a week on that topic before re-testing with a different seed.
5 or 6 out of 10
Some core ideas are shaky. The pattern matters more than the score: two misses in the same topic is a gap; misses scattered across topics usually means reading the question too fast. Either way, the Skills Check will tell you which.
4 or fewer out of 10
Foundations from an earlier year are probably missing, which is common and fixable. Try the quiz one year level down to confirm, then talk to a tutor about a short catch-up plan rather than more of the same practice.

Frequently asked questions

Is this Year 1 addition and subtraction to 20 quiz free?

Yes, completely: no sign-up, no email, no payment, and you can take it as many times as you like. It is one of 3,261 free practice questions RHZ Tutoring publishes across Prep to Year 12. Press New set of questions, or add ?seed= to the address, for a different selection from the same topic.

Why only 10 questions on one topic?

Because a single-topic set is the most precise free check available: if the score is low, the gap is in addition and subtraction to 20 and nowhere else. There are 10 eligible questions on this topic in our Year 1 Maths bank, so several different sets are available before any repeat.

Where do the addition and subtraction to 20 questions come from?

From RHZ Tutoring's own Year 1 Maths question bank, written to the Victorian Curriculum, checked by a tutor and passed through an automated quality gate. The same bank feeds our tutoring sessions and the free Skills Check. This topic includes a few stretch-tier questions so that a full set is available.

What should I do if the score is low?

Read the explanation for each incorrect answer first; most gaps in addition and subtraction to 20 are one of the misconceptions listed on this page. Then try a second set a few days later. If it is still low, the free Skills Check will show whether the gap is confined to this topic, and a tutor can build a short catch-up plan.

Is there a mixed Year 1 Maths quiz?

Yes. The Year 1 Maths quiz spreads ten questions across every topic for the year, and the hub lists topic quizzes for every year level from Prep to Year 12.
