How far can you get before a problem stops you?
Build a double-bar chart
Students drag paired bars up and down to represent a two-group data table. Checks every bar against the data.
Build the Solution
Watch a two-step equation solve itself, one move at a time.
Combine like terms
Students simplify a polynomial by combining coefficients themselves, term family by term family. Rebuilt from Sean's slider-scrubbed worked example, made active.
Distribute & Solve
Sean's step-by-step distributive-property solver, running live in Glyph.
Find the Median
Build a data set and locate its middle, step by step.
Find the missing value
A data table has a blank; students type the value that makes a target statistic true, with the live statistic shown. From Sean's Mean question bank.
Fractions on the strip
A whole strip spans the board; students drag markers to unit fractions, discover equivalence, and compare sizes by position. Rebuilt from Sean's fraction-strip manipulative with checkable targets.
Guided derivation (WeDo style)
A worked problem the student completes themselves: place the given numbers into the setup, then fill each derivation line. Show Me help is available, and logged. Straight from the WeDo percent prototype.
Hit the target measurement
Students adjust a shape's dimensions with sliders to hit a target area or volume shown live, Sean's 'choose the radius closest to 500 cm³' question class, made hands-on.
Integer addition & zero pairs
Adding integers on the number line: each +1/−1 pair cancels to zero. Students drag to the result and count the canceling pairs. Completed from Sean's chip-model prototype, which had the manipulative but no targets.
Is the statement true?
Students judge membership and subset statements written in symbols, dragging TRUE or FALSE. The point Sean's page makes: an element belongs to a set, a set is contained in a set, and swapping the symbols changes what is being claimed.
Name that number (operation vocabulary)
Sum, divisor, product, prime, GCF, LCM: students prove they know each term by typing the number it names. Rebuilt from Sean's self-graded flashcards with real checking.
Order of operations, step by step
A guided derivation where the student computes every stage themselves, parentheses, exponents, multiplication, addition. Rebuilt from Sean's three walkthrough variants, made active instead of click-to-reveal.
Parameter or statistic?
Students decide whether a reported number describes a whole population or a sample drawn from it, dragging into one of two zones. Sean pairs his examples so the same context appears both ways, which is what makes the distinction bite.
Partial products (area model)
Multi-digit multiplication the box-model way: students decompose by place value, compute every partial product, and sum. Rebuilt from Sean's staged typed worksheet.
Percent proportions, step by step
A worked problem the student completes themselves: place the given numbers into the setup, then fill each derivation line. Show Me help is available — and logged. Straight from the WeDo percent prototype.
Polynomial end behavior
Degree and leading-coefficient sliders drive a live power function; students produce each of the four end-behavior cases on demand. Consolidates Sean's three end-behavior builds.
Prime factor tree
Students grow a factor tree by always extracting the smallest prime, then assemble the prime factorization with exponents. Rebuilt from Sean's clickable SVG tree.
Radius and circumference
Students grow a circle with a radius slider and watch C = 2πr update live, then hit a target circumference and compute one by hand. From Sean's circle explorations.
Solve one-step equations (integers)
Students solve x + p = q and px = q where coefficients and solutions run negative. Identical skill to the whole-numbers variant, the number domain is the only thing that moved.
Solve Step-by-Step
Work each step yourself, or skip and watch.
Tune an equation to a solution
Students set sliders for the coefficients of an equation (including negative values) so it has a required solution, Sean's working-backwards questions made manipulable. The solution readout updates live. Grade 7+: coefficients range negative, above grade-6 scope.
Which region does the expression name?
Two overlapping sets, four regions. Students drag a marker into the region a set expression describes, one expression at a time, including the complement and the difference. From Sean's clickable double Venn diagram.
Which region does the expression name? (three sets)
Three overlapping sets and eight regions, where the same expressions get genuinely harder: the centre is in all three, and a two-set intersection now has to EXCLUDE the third. From Sean's triple Venn highlighter.
Write the rule for Figure n
The harder half: not a count, but the rule itself. Students fill in the coefficient and the constant for the nth figure, then test it against a figure they can still see. From Sean's nth-term pattern practice.
