Skip Counting by 100s Task Box

About this resource

EVERYTHING INSIDE — 22 pages, 150 fillable fields

• 18 skip-counting-by-100s cards across 3 levels (6 cards each), every card a four-number run with one blank the child works out — plain printed numerals, no pictures
• Every level counts by the same hundred; what changes level to level is the choice count, where the blank sits, and the range: Level 1 runs 100 to 1,000 (two choices), Level 2 runs 100 to 2,000 (three choices), Level 3 runs 100 to 3,000 (four choices)
• Every card twice: accent-colored tiles for a laminated classroom box and black-on-white ink-saver tiles for the photocopier
• A hundreds reference page (color and ink-saver), showing the full count for all three ranges — 100 to 1,000, 100 to 2,000, 100 to 3,000 — in order
• An answer key listing every run by level, its answer, and the numbers printed on the card
• 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: 25 lines in 6 groups (spoken lines for running the box, written starters for the note afterward)
• Start Here, a contents page with page thumbnails, and a "what's next" back page

A task box built around one skip count that keeps showing up once a student is working with three-digit numbers — hundreds — asked the same way every sort-and-sequence set in this collection asks: read the run, work out what is missing, mark one choice. Unlike its two siblings (2s/5s/10s and 3s/4s/6s), every level here is the SAME skip count; the levels get harder by widening the number range and adding choices, not by swapping the step. It carries the same data sheet, graph and phrase bank as the rest of the collection, so this practice turns into a line on a page a case manager can bring to a meeting.

Three Levels, Same Hundred, A Wider Range Each Time

• Level 1 — 6 cards, 100 to 1,000, two numbers to choose from. The blank sits at the end of every run ("100, 200, 300, __"), and the wrong choice is always at least three hundreds away from the answer, so this opening set is forgiving on purpose.
• Level 2 — 6 cards, 100 to 2,000, three numbers to choose from. The blank hides inside the run, never at either end, so the child has to check the number on both sides of the gap instead of just riding the count forward. Every number offered is still a multiple of one hundred, and no wrong choice sits closer than two hundreds to the true value.
• Level 3 — 6 cards, 100 to 3,000, four numbers to choose from. The blank opens the run ("__, 500, 600, 700") — the child has to work out what came before the numbers already printed — and one wrong choice is a near-miss: the number right after the blank, already sitting on the card in plain view.

Moving up a level widens the range and adds a choice, so a student cannot answer from card position alone. Nothing on a card names 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 tile on every page is a plain printed numeral, drawn the same way in both the color set and the ink-saver set. There is no picture library to run thin 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 reference page 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 records one thing: whether the missing hundred on each card was marked correctly.

Who This Is For

Special education teachers and paraprofessionals running independent work stations or task box rotations with students working on skip counting by hundreds and reading three- and four-digit numbers, 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.
