Shaded is negative, open is positive

5 shaded and 3 open circles equals 2 red (-2)

200

Create the circle image for this equation: -8-3

Shaded is negative, open is positive

8 shaded and 3 more shaded circles (-11)

300

Create a number line to represent this equation: 

5- (-3)

start on 5 and jump forward 3 spaces, landing on 8

400

Create a number line to represent 4⋅ -2

start at 0 and skip count by -2 four times
