Ask students to find the TIMS Radio Tower page in
the Student Activity Book. Direct each student to
build a cube model of the tower on this page and
complete Questions 1–4. To complete these questions,
students are asked to find the floors and volume
of their cube model and then communicate their
solution strategy. Before they begin work, show a
display of the Math Practices page from the Student
Activity Book Reference section and review
Expectation 5, Show my work and Expectation 6, Use
labels.
Use the TIMS Radio Tower pages with the Feedback Box in
the Student Activity Book to assess students’ abilities to
measure the volume of a cube model by building a model
and counting cubic units [E3]; solve problems involving
volume using repeated addition and skip counting [E1];
represent the volume of a cube model using symbols and
connecting cubes [E2]; show work [MPE5]; and use labels to
show what numbers mean [MPE6].
Targeted Practice. Place 30 connecting cubes, a calculator,
and the Rules for Cube Buildings
Master from Lesson 1 in a
learning center. Working with a partner, one student builds a
tower using between 10 and 30 cubes that follows the rules
for building cube models. When the building is complete, the
other student uses strategies to find the volume of the
building. He or she shares their strategy with their partner
who checks their work for accuracy. Partners can then
change roles and repeat the process.
