Halves Recognition Sort Task Box

About this resource

EVERYTHING INSIDE — 22 pages, 151 type-in fields (verified: pypdf field count on the shipped PDF)

• 72 bar cards across 3 levels (26 rounds: 12 rounds of 2 cards, 8 rounds of 3 cards, 6 rounds of 4 cards), every card a plain CSS rectangle split into equal segments, some shaded, sorted into a SHOWS ONE HALF bin or a NOT ONE HALF bin
• Every bar is a rectangle, never a circle or pie slice — a clean row of bordered segments, nothing to misread as a clock face
• Every card twice: accent-filled segments for a laminated classroom box and a diagonal hatch pattern on black-on-white ink-saver tiles for the photocopier — the shaded/unshaded split never depends on color alone, even on a black-and-white copy
• A two-bin sort mat (color and ink-saver), SHOWS ONE HALF and NOT ONE HALF, six card-sized slots in each bin, each bin headed by its own small sample bars
• An answer key listing every round by level, its shows-one-half bars and its not-one-half bars, each written as shaded segments over total segments exactly as the card prints it
• A task box data sheet (16 rows: date, level, rounds given, cards correct, cards given, percent, help given, initials)
• A percent graph, 14 sessions across, with a level box under each session
• A filled example — an invented student, 8 sessions, every percent re-counted from its own row
• A family practice page with six of the same bars and the two bins
• A phrase bank: spoken lines for running the box and written starters for the note afterward, in 6 groups
• Start Here, a contents page with page thumbnails, and a "what's next" back page

A task box built around one fraction-sense skill the collection didn't have yet: recognizing when a bar shows exactly one half versus close to it but not. It comes with the same data sheet, graph and phrase bank as the rest of the collection, so independent work turns into a line on a page a case manager can bring to a meeting.

Three Levels, Each Testing Something Different

• Level 1 — 12 rounds, 2 cards each. The SHOWS ONE HALF card is always a 2-part bar with 1 part shaded; the NOT ONE HALF card is always a 4-part bar with 1 or 3 parts shaded — a different bar entirely, so the first sorts are nearly impossible to get wrong just by looking.
• Level 2 — 8 rounds, 3 cards each. Every bar is now split into 4 equal parts in both bins, and the split is not always one-and-two, so a child has to count the shaded parts on every card, not just glance at how full it looks.
• Level 3 — 6 rounds, 4 cards each, cut as a 2x2 block. Every bar is split into 6 equal parts in both bins — 2 of 6, 4 of 6 and 5 of 6 all look close to half without being it, so every card takes counting the shaded parts against the total.

Nothing on a card says its level except a dot code in the corner (one, two or three dots), so a mixed-up box sorts itself back together.

NO PIE SLICES, ON PURPOSE — every fraction on every page is a rectangle split into equal CSS segments, drawn the same way in both the color set and the ink-saver set. There is no circle, no wedge angle and no clock-face to misread; the only thing a child reads is how many of the equal parts are shaded.

What This Is, And What It Is Not

It is a fillable PDF: type into the data sheet, the graph header, the family page and the example-style notes, or print and use a pen. The card pages and sort mat print on cardstock or plain paper and cut along dashed lines. It works offline with no account or subscription. It is NOT an editable online slideshow or word-processor document, and it is not a test of anything.

It carries no prompt hierarchy, fading schedule or mastery rule, and it does not decide what a percent means for a student or when to move up a level. The goal line and the criterion field are blanks for your district's own wording and your team's own number. It measures one thing: cards placed in the correct bin.

Who This Is For

Special education teachers and paraprofessionals running independent work stations or task box rotations with students working on fraction sense (recognizing one half), case managers who need that practice to show up as data, and the families who get the practice page sent home.

More In The Collection

This is one set in the Task Box Collection; more sort, counting and sequencing boxes are being added to the collection regularly, all on the same cards-plus-data shape.
