Odd or Even Number Sort Task Box 1-100

About this resource

EVERYTHING INSIDE — 22 pages, 151 type-in fields

• 72 numeral tile cards across 3 levels (26 rounds: 12 rounds of 2 cards, 8 rounds of 3 cards, 6 rounds of 4 cards), drawn from the full 1-100 range, every card a plain CSS digit tile sorted into an ODD bin or an EVEN bin
• Every card twice: accent-colored tiles for a laminated classroom box and black-on-white ink-saver tiles for the photocopier — plain printed numerals, no picture library either way
• A two-bin sort mat (color and ink-saver), ODD and EVEN, six card-sized slots in each bin
• An answer key listing every round by level, its odd numbers and its even numbers, plus every distinct number used in the box
• 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 cards 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

Built for the student who has outgrown a 1-20 odd/even sort but still needs the number read, not guessed from how long it is. Three levels push the same skill further across the number line, ending in a set of two-digit windows that straddle a round number — the exact place a child who sorts by "how the number looks" starts guessing wrong.

Three Levels, A Wider Range At Each One

• Level 1 — 12 rounds, 2 cards each. Numbers 1-24, and every round pairs one odd number with one even number — an easy, checkable band before the range opens up.
• Level 2 — 8 rounds, 3 cards each. Numbers 6-94, spanning nearly the whole range, and the split is not always one-and-two, so every card gets checked on its own.
• Level 3 — 6 rounds, 4 cards each, cut as a 2x2 block. Each round is a tight four-number window that straddles a multiple of ten somewhere in the range — 18 to 21, 38 to 41, all the way to 97 to 100 — so a child cannot sort by which decade a number lives in; only the ones digit decides the bin.

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 PICTURES, ON PURPOSE — every numeral on every page is plain printed text, drawn the same way in both the color set and the ink-saver set. There is no picture library to run out of and no image to misread; the only thing a child reads is a number.

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, now across a hundred numbers instead of twenty.

Who This Is For

Special education teachers and paraprofessionals running independent work stations or task box rotations with students ready to extend odd/even number sense past 20, 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. The 1-20 version of this same sort is also in the store for a student who isn't at this range yet.
