This is a spreadsheet of addition tables from 0 to 10 that is print-ready to be cut into narrow strips. Each strip has 25 addition sentences, ranging in addends from 0 to 12 for 1s, 2s, etc... to be completed with a minute timer as a math warm-up option.
--I print up to 50 of each strip, cut them, leave them in small narrow trays (or piles) on a countertop and tell students to remember which strip they are working on for mastery. I then log their mastery on an addition record sheet. This can be used as a whole class warm up, or as a partner task during math centers for automaticity.
