Rule
CCSS.MATH.CONTENT.7.NS.A.2
Description: Explicit direct instruction on drawing the "Tic-Tac-Toe" visual graphic organizer to memorize sign rules. Students will sort a list of pre-solved equations into "Positive Answer" or "Negative Answer" columns based purely on the signs before using a calculator to find the numerical product.
Purpose: To isolate the cognitive task of determining the sign from the arithmetic calculation, preventing working memory overload.
DOK Level: DOK 1 (Recall & Reproduction) - Recalling a sign rule and applying a standard, single-step classification procedure.
Pre-printed Tic-Tac-Toe rule cards taped to desks; color-coding negative signs in red ink; chunked worksheets (only 4 problems per page).
Adapted Quiz: 10 questions. The numbers are already calculated (ex. -4 x 3 = __ 12). The student only has to select if the 12 should be a positive (+) or a negative (-) from a drop-down or circled choice.
