This download contains a set of 20 colored and 20 black and white task cards to support CCSS 6.NS.6. The questions cover sections a-c in the standard. The cards ask students to work with rational numbers on both a number line and a coordinate plane. Students must also use the terminology "opposite" when writing mathematical statements. These can be used on a math wall, in small groups, for morning warm ups and more. The answer key, extra cards with grids and number lines, and 4 recording sheets are included.
