  2. Regrouping (carrying) with Mixed Numbers • This happens in addition when the two fractions add up to more than one. • We have to regroup in subtraction because the top number fractional part is smaller than the bottom number fractional part. • In addition we have to regroup in the Simplify step. • In subtraction we have to regroup in the Alter step. • We can still use LAPS to solve the problem.

  4. How do we make a tessellation with a complex shape? • Step 1: Draw a shape • Step 2: Create a pattern by flipping, sliding or turning the shape. • Step 3: Color the pattern with only a few (2 or 3) colors.
