Ten More or Ten Less Within 1,000 Task Box

About this resource

EVERYTHING INSIDE — 22 pages, 150 type-in fields

• 18 ten-more/ten-less cards within 1,000 across 3 levels (9 “ten more” cards, 9 “ten less” cards), every card one plain CSS numeral tile, its fixed direction printed on the card, and a row of numeral choice tiles the child marks
• 6 of the 18 cards cross into a new hundred (for example 395 ten more is 405, or 601 ten less is 591) — the one genuinely new wrinkle a within-1,000 box has that a within-100 box never meets, called out on the card itself, the answer key and the family page, not left for a student to discover unguided
• 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 number-line reference page (color and ink-saver): eight anchor numbers, each shown with its own ten-less and ten-more neighbor, three of the eight anchors (295, 398 and 601) deliberately sitting at a hundred's edge
• An answer key listing every card by level, with its starting numeral, its fixed direction and its choices, the answer marked in bold and a star flagging every card that crosses a hundred
• A task box data sheet (16 rows: date, level, cards used, 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 built entirely from the box's six hundred-crossing 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 Distractor, Not The Direction

Every level mixes "ten more" and "ten less" cards roughly evenly, so a student can never answer by always adding — the instruction printed on the card is the only thing that says which way to go. The same ramp as the 1-100 box, now proven at three digits, including across a hundred boundary.

• Level 1 — 6 cards, 2 choices. The wrong choice is that same starting numeral's answer going the OTHER direction: twenty away from the true answer, and clearly too big or too small, an easy give-away even on a card that crosses a hundred.
• Level 2 — 6 cards, 3 choices. A numeral one away from the true answer (the kind of slip a child makes counting by one instead of ten — on a crossing card this sits just short of or past the new hundred) plus the same wrong-direction choice.
• Level 3 — 6 cards, 4 choices. Both a one-away AND a two-away near miss live on the card at once, plus the wrong-direction choice — the hardest discrimination in the box, and on a crossing card both near misses sit on the far side of the new hundred from the start.

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 and a direction.

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 number-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 ten-more-or-ten-less tile correctly marked.

Who This Is For

Special education teachers and paraprofessionals running independent work stations or task box rotations with students working on three-digit 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 place-value boxes are being added to the collection regularly, all on the same cards-plus-data shape.
