Get help with Mathematics, Grade 1
Most tutoring makes your child sit through material your child already knows. MapleMind flips that: pick the exact skill that's causing trouble — any of the 24 below — and the tutor teaches just that one, step by step, as many times as it takes. Ask questions in plain words, any time of day, in English, French, or 12 other languages.
The official Prince Edward Island Mathematics, Grade 1 curriculum
Prince Edward Island defines Mathematics, Grade 1 by strands and outcomes. MapleMind teaches the same curriculum reorganized for one-skill-at-a-time tutoring — the table shows exactly where every official strand lands, and the ministry's own wording is quoted under each unit below.

How MapleMind teaches Mathematics, Grade 1 — every unit, lesson, and skill
Every skill below runs as a short session: a plain-words lesson, a worked example, solving it together, then a five-question skill check that earns up to three stars. Guided Mode keeps it teaching instead of answer-handing — turning it off needs a parent's password.
Unit 1NumberOfficial strand · Strand N
Counting and skip-counting to 100, seeing small amounts at a glance, counting sets, numbers to 20, comparing and estimating, equal groups, one and two more or less, and first addition and subtraction facts to 20.
Counting and Skip-Counting
- Counting forward and backward by 1s1.N1 — Say the number sequence by 1s, forward and backward, between any two given numbers from 0 to 100.
- Skip-counting by 2s, 5s, and 10s1.N1 — Skip-count forward by 2s to 20, and by 5s and 10s to 100, starting at 0, using a hundred chart or a number line.
Counting Sets
- Seeing how many at a glance1.N2 — Recognize at a glance and name familiar arrangements of one to ten objects or dots, without counting one by one.
- The last number tells how many1.N3 — Count a set and understand that the last number said identifies how many, and that a set has only one count no matter the order counted.
- Counting on from a number you know1.N3 — Count a set by counting on from a known quantity instead of starting over at one.
- Counting a set in equal groups1.N3 — Count a set by using parts or equal groups, such as grouping objects into pairs and counting by 2s.
Numbers to 20
- Showing numbers to 201.N4 — Represent and describe numbers to 20 concretely with manipulatives, pictorially with drawings, and symbolically with numerals.
- Showing a number as equal groups1.N6 — Show, concretely and pictorially, how a given number can be represented by a variety of equal groups, with and without singles left over.
Comparing Sets and More or Less
- Comparing sets with a referent1.N5 — Compare sets containing up to 20 elements using referents, and describe them with comparative words such as more, fewer, or as many.
- Matching sets one to one1.N5 — Compare two sets using one-to-one correspondence and solve story problems that involve comparing two quantities up to 20.
- One more, two more, one less, two less1.N7 — Identify the number, up to 20, that is one more, two more, one less, and two less than a given number.
Addition and Subtraction to 20
- Talking about adding and taking away1.N8 — Use familiar and mathematical language to describe additive and subtractive actions from everyday experience, for numbers with answers to 20.
- Solving adding and taking-away problems1.N8 — Create and solve problems in context that involve addition and subtraction with answers to 20, using concrete and visual representations.
- Modelling and recording number sentences1.N8 — Model addition and subtraction with concrete and visual representations and record the process symbolically as a number sentence, for answers to 20 and their corresponding subtraction facts.
- Counting on and counting back to add and subtract1.N9 — Describe and use the counting-on and counting-back mental math strategies for basic addition and subtraction facts to 18 (memorization not intended).
- Making 10 and using doubles1.N9 — Describe and use the making-10 and doubles mental math strategies for basic addition facts to 18.
- Using addition to subtract1.N9 — Describe and use the using-addition-to-subtract mental math strategy for basic subtraction facts to 18.

Unit 2Patterns and RelationsOfficial strand · Strand PR
Repeating patterns, translating patterns from one form to another, and equality as a balance.
Repeating Patterns
- Describing repeating patterns1.PR1 — Describe repeating patterns of two to four elements by naming the part that repeats (the core), using manipulatives, diagrams, sounds, and actions.
- Copying, extending, and creating patterns1.PR1 — Reproduce, extend, and create repeating patterns of two to four elements using manipulatives, diagrams, sounds, and actions.
- Translating a pattern to a new form1.PR2 — Translate a repeating pattern from one representation to another, such as turning a colour pattern into a sound or action pattern with the same core.
Equality as a Balance
