This packet includes:
-a parent letter
-color-coated subtraction tables for each level
-color-coated flashcards for each level (to be kept at school or emailed home),
-a subtraction rainbow recording sheet. (to color and make into Rainbow Subtraction Master crown once students have completed all the levels...the student's name goes on the bottom stripe).
I created Rainbow Subtraction Facts to help my students master all differences to 10, the core fluency goal for the Common Core mathematics standards. Students begin on the red level (subtract 0 and 1) and a color-coated subtraction chart is kept in their homework folders. Parents help them master small sections of the table at a time. When my parents think their children have memorized the facts, they send the chart back in signed and I assess the students using the included flashcards. When they have memorized all the red facts, they graduate to the orange level. When they learn all the purple facts, they earn the title Rainbow Subtraction Master and I make them a crown by cutting out the rainbow and affixing it to a sentence strip crown.
