Rounding to the Nearest Ten Task Box

About this resource

EVERYTHING INSIDE — 22 pages, 150 type-in fields (verified: pypdf field count on the shipped PDF)

• 18 rounding cards across 3 levels, every card one plain CSS numeral tile, a fixed "Round to the nearest ten" instruction printed on the card, and a row of numeral choice tiles (every choice a multiple of ten) the child marks
• 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 rounding-line reference page (color and ink-saver): eight rows, one per decade, each showing its lower ten, its exact tie, and its upper ten, with the 0–4-rounds-down / 5–9-rounds-up rule printed beside the arrows
• An answer key listing every card by level, with its given number and its true nearest ten, the answer marked in bold
• A task box data sheet (16 rows: date, level, cards used, cards correct, cards given, percent, help given, initials)
• A percent graph, 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
• 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

Three Levels, Ramped By The Ones Digit

Every level mixes numbers that round up and numbers that round down roughly evenly, so a student can never answer by always picking the same direction — the ones digit, not the position on the page, is what decides the answer.

• Level 1 — 6 cards, 2 choices. Numbers ending in 1, 2, 8 or 9: an easy call. The wrong choice is the other bracketing ten, a whole decade away.
• Level 2 — 6 cards, 3 choices. Numbers ending in 3, 4, 6 or 7: a real judgment call. The other bracketing ten plus one more decoy a further decade out.
• Level 3 — 6 cards, 4 choices. Exact ties (ending in 5, always rounded UP, the standard convention) mixed with numbers ending in 4 or 6 that sit right next to a tie. Three decoy tens march away from the true answer at once — the hardest discrimination in the box.

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 rounding-line reference 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 with the nearest-ten tile correctly marked.

Who This Is For

Special education teachers and paraprofessionals running independent work stations or task box rotations with students working on place value and number sense, 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.
