Ages 6-7
Grade 1 math
Grade 1 turns counting into arithmetic. Facts within 10 become quick, and children learn to think in tens and ones.
What grade 1 usually covers
An ordinary elementary scope and sequence, the one the sets here follow. Schools differ by a few months either way.
Addition and subtraction within 20
Counting on, making ten, doubles and near doubles. Facts within 10 should be known by heart by the end of the year.
Tens and ones
Numbers to 120 as groups of ten and some ones: 47 is 4 tens and 7 ones. Ten more and ten less without counting.
Comparing
Which is bigger, 36 or 63? The tens decide first. The symbols >, < and = appear this year.
Adding within 100
A two-digit number plus a one-digit number, or plus a multiple of ten, with drawings and number lines rather than columns.
Time, measuring and shapes
The clock to the hour and half hour, lengths measured in whole units laid end to end, and halves and quarters of a shape.
Practice for grade 1
The set below is on the grades 1–2 band: sums and differences within 20 and simple two-digit adding. Five minutes most days, and stop while it is still going well.
Work it out.
Ten questions at a time, marked as you go. Pick a skill above and start; nothing to sign up for, and the set works offline once the page has loaded.
Pages for this grade
Each has the method written out, worked examples, the facts worth knowing and ten practice questions with answers.
Common questions
- Which facts should be automatic by the end of grade 1?
- Addition and subtraction within 10, and the doubles to 10 + 10. Facts to 20 are met this year but usually become automatic in grade 2.
- Is counting on fingers a problem in grade 1?
- No. It is a stage. What moves a child off fingers is knowing the doubles and the pairs that make ten, not being told to stop.
