Upon completion, instruct students to exchange their
Area Riddles with a partner. Ask them to compare
the shapes they created in Question 5 and to check
the area.
- What is the same about your shape and your partner's
shape in Question 5? (Both shapes have an
area of 12 square centimeters.)
- How many fourths are in your shape? (2 fourths)
- How many fourths can you put together to make
one-half? (2 fourths make one-half.)
- How many halves are in your shape? (3 halves)
- How many whole square centimeters can you
make with 3 halves? (1 and then there is one-half
left over.)
- Did you put any halves and fourths together? (I
put the leftover half and the 2 fourths together to
make another whole square centimeter.)
Assign the Area Questions page in the Student
Activity Book for students to complete individually.
Students will compare two different shapes with the
same area. They will measure area by counting both
whole and fractional parts of square centimeters.
Use the Area Questions page and the Feedback Box in the
Student Activity Book to assess students' abilities to find the
area of a shape that includes fractional parts using counting
and reasoning strategies [E8]; recognize that different shapes
can have the same area [E9]; and use numbers, words, and
square units to report area measurements [MPE6].
Place a copy of the first page and copies of the second page
of the Put the Pieces Together Assessment Master from the
Teacher Guide in a learning center to provide targeted
practice with halves and fourths. See Materials Preparation.
