Activities to download and open on your iPad. These are not the ones the app ships with — those are already installed. Free, and once one is on the device you can rewrite it with your own AI assistant.
Comparing, ordering and adding fractions — built around the one idea that makes them make sense: every fraction is a place on a line.
questions and picturesPlace value, rounding and the shortcuts that quietly stop working. Built for the moment a class realises "just add a zero" was never the rule.
questions and picturesNewton's first two laws, aimed squarely at the misconceptions: that motion needs a force to keep it going, and that gravity takes a break at the top of a throw.
questions and picturesThe particle model, and the four or five places students quietly stop believing it — melting versus dissolving, where mass goes, and why boiling water refuses to get hotter.
questions and picturesThe solar system, aimed at the three explanations almost everyone gets wrong: what causes day and night, what causes the seasons, and why the Moon changes shape.
questions and picturesCell structure by pointing rather than reciting — find the part on a real diagram, then work out what it must be for.
questions and picturesOrgans and what they are for, found by pointing at a diagram rather than recited from a list — then the two systems that keep everything else supplied.
questions and picturesContours, compass and scale, read off one map rather than described in the abstract. Two rounds ask the class to point at the answer.
questions and picturesChronology and evidence. Two ordering rounds to build a sense of when things happened relative to each other, and three on how historians decide what to believe.
questions and picturesGrammar as a tool rather than a rulebook: what a sentence needs to stand up, how word order carries meaning, and how a passive verb hides who did it.
questions and picturesReading a chart, and the three tricks that make an honest chart tell a lie: a cut axis, a missing baseline, and a cause invented from a coincidence.
questions and picturesScam messages, passwords, and what a padlock in the address bar does and does not promise. Built around real tricks rather than a list of rules.
questions and picturesSix questions with no right answer. The board shows the split, and the split is the discussion — built for tutor groups, staff meetings and the first day of a course.
questions and picturesA race through six pieces of code. Say what each one actually does to unlock the next — first team through all six wins.
contains a programFind the defect in process sketches, specs, forms, and data tables.
questions and picturesPredict user behavior on service screens.
questions and picturesTwo ways, both on the iPad running Halqa.
From a link. Tap Copy link on an activity, then in Halqa's catalog choose Add an Activity → From a Library Link and paste it. This is the only time Halqa uses the internet, and it accepts addresses from this site and nowhere else.
From a file. Download it in Safari, then open the file and choose Halqa. This route works for every activity, including the one here that contains a program — Apple's rules do not allow an app to download code, so that one has to arrive as a file. Either way it appears in the catalog and works with no internet from then on.
Everything here fits in well under a megabyte, so a whole shelf downloads over the slowest staff-room Wi-Fi.
Most of these are questions and pictures — data, with nothing in them that can execute. One activity here contains a program that defines its own rules, which is how an activity can be a race rather than a quiz. Your iPad installs those but will not run one until you have seen what it declares and allowed it.
Every activity on this page has been checked for anything that could execute where it should not, and every program has been read by a person. You can and should check any pack yourself before installing it — including these.
