Multiply and divide fractional numbers to any place-value.
Utilize the standard algorithm to divide fractions.
With two fractions, find the reciprocal of the 2nd fraction, replace the ÷ with x, multiply numerators and denominators, simplify.
With a whole number by a fraction, convert the whole number to an improper fraction, find the reciprocal of the 2nd fraction, replace the ÷ with x, multiply numerators and denominators, simplify.
Inverse, Mixed number, Improper fraction, Reciprocal, Cross cancellation, Reduce, Simplest form
1. Students solved problems that involved multiplication and division of mixed numbers and improper fractions.
2. Students solved equation problems by using the inverse of division, which is multiplication, when the problem involved division.
3. Students practiced cross cancellation to efficiently reduce the fraction to simplest form.
Reason with angle relationships and types.
Identify the similarities and differences among different angle relationships.
Define supplementary angles as two angles that add up to 180° (or a straight angle).
Define complementary angles as two angles that add up to 90° (or a right angle).
Define adjacent angles as two angles that share a common side and a common vertex, but do not overlap.
Complementary angles, Supplementary angles, Angles, Congruent, Adjacent,
1. Students practiced solving for complementary angles adding up to 90 degrees and supplementary angles to 180 degrees.
2. Students solved for congruent angles and identified adjacent angles.
