Each lesson is a short, focused practice game built for projection, centers, or one-to-one devices. New lessons are added regularly — multiple lessons are live, and more are on the way.
Math fluency
Generated practice: every student gets the same set of problems, produced from a recorded seed so the worksheet is reproducible and gradable.
Timed-free practice with whole-number addition and subtraction. The teacher chooses the digit range, whether problems carry or borrow, and how many questions; every student in the class gets the same generated set, and answers are checked on the server.
Fact practice from the 5s to 2-digit by 2-digit, with division either exact or carrying remainders. The teacher picks the operations, the number range, and whether to drill a single fact family; every division problem is built from a known product, so it always comes out exactly as intended.
Naming, matching, comparing, and simplifying fractions, with bar and pie models drawn on the page. The teacher picks one skill or all four; comparisons are answered by choosing the relation in words, so no one is defeated by finding the < key.
Adding, subtracting, multiplying, and dividing fractions, with like or unlike denominators and optional mixed numbers. Every result is computed exactly rather than in decimals, so a third plus a sixth is exactly a half.
Evaluating expressions with PEMDAS, building up from multiply-before-add to parentheses and exponents. Every problem is constructed so that working left to right gives the wrong answer — so the set really practises the order rather than rewarding a student who ignores it.
Number sense
What the digits in a number mean, and how numbers relate to each other — the foundation the four operations stand on.
What the digits in a number actually mean: the value of a digit, the name of its place, expanded form, word form, and reading a written number back into digits. Numbers run from tens to millions, with or without the zeros that make place value matter.
Deciding which of two numbers is larger, and putting a whole set in order. Three difficulty levels change how much the numbers have in common — at the hardest, every digit but the last matches, so they have to be compared place by place.
Reading an analog clock, from o’clock all the way to the minute. Each clock is drawn on the page with the hour hand correctly advanced between the numerals — at half past three it sits half-way to four, which is where most wrong answers come from.
Skip-counting sequences with one or two numbers hidden. Every sequence keeps a pair of neighbouring numbers visible, so the pattern can always be worked out from what is shown — and each missing number is answered on its own line.
A real month is drawn as a calendar and every question is answered by reading it: which day of the week a date falls on, the date of the second Tuesday, and counting days forward and back.
Language
Grammar practice drawn from the InstructorWeb grammar worksheets: the same questions a student would answer on paper, checked on the server and reported back to the teacher.
Naming the job each word does in a sentence — nouns, verbs, adjectives, adverbs, pronouns and the rest. Every question is drawn from an InstructorWeb grammar worksheet, so the digital practice and the printable ask the same things.
Verb forms and tenses: making the verb agree with its subject, past and future, and the verb patterns that trip students up. Drawn from the InstructorWeb grammar worksheets.
How sentences are built: subjects and predicates, clauses and phrases, run-ons and fragments, and the four sentence types. The largest of the grammar sets.
The word pairs and usage rules that cause the most red pen: a and an, affect and effect, among and between, and their many relatives.
Commas, apostrophes, quotation marks, colons and capital letters — the marks that decide what a sentence means.
