Reveal a number string, gather silent think time, then stamp up each student’s strategy as they share.
Pick a category, then press “New number talk” to draw a prompt from the bank — or type your own below.
Press “New number talk” to reveal a prompt.
Or type your own prompt
One expression per line. One line makes a single computation (e.g. 27 x 4); 2–4 related lines make a number string revealed one at a time (e.g. 8 + 5 / 18 + 5 / 28 + 5).
My Number Talks
Your own saved favorites — unlike the session history below, these stay on this device across visits. Star a prompt above to add one, or choose “My Number Talks (only)” from the category dropdown to draw from them at random.
Quick Image Options
Flash a set of dots for a couple of seconds, then hide it. Ask “How many did you see? How did you see them?” before revealing the count — the routine builds subitizing and number sense, not one-by-one counting.
Strategy-Sharing Board
One card per student who shares. Jot the gist only — a name (optional — start typing to autocomplete from any roster saved on this device via Class Roster Hub or Name Picker) and a line or two of their reasoning. This is meant to be fast to fill in while class is running.
No strategies stamped up yet — add a card as students share out.
Class Strategy Library (grows all year)
Unlike the board above — which clears out — a strategy saved here stays on this device across every session this year, and prints one full-page poster per strategy for the wall. Use “+ Save to library” on a card above while it’s still on the board, or add one directly below.

String History Log (this term)
Every string drawn or used on this device, oldest reload and all — unlike the session list above, this one survives a reload. A fresh pull avoids whatever's most recent in this log, so repeats stay rare across the whole term. Clear it at the start of a new term to start avoiding repeats from scratch.
Nothing logged yet — it fills in as you draw or use number talks.
