7. Step 2 : Add the same number of blocks to each side to make zero pairs. 2x – 5 = 3 - - + = +
8. Step 3 : Remove Zero Pairs from both sides (if needed). 2x – 5 = 3 - - + = +
9. Step 4 : Ask, “How many x’s are there?” Answer: ____ Divide unit blocks into ___ groups. - - + = +

11. Flow Maps: One-step Equations Words Symbolic Record the answer Remove zero pairs Add the same number to each side to make zero pairs Write/draw/model the equation X = -2 X = 1 + (-3) 3 + x = 1 (+) -3 =-3 3 + x = 1
12. Flow Maps: One-step Equations Words Symbolic Record the answer Remove all but ONE grop from EACH side. Ask: “How many “x’s?” Divide (unit blocks/tallies) by the answer. Write/draw/model the equation X = 4 4x = 16 4 4 There are 4 x’s 4x = 16
