Estimation activities encourage students to make connections among the
mathematics concepts they are learning and the skills they are
In this multipart video example, the class discussions and
the decisions the teacher makes contribute to students' opportunities to
connect their understandings of number, measurement, geometry, and data
in order to make estimates. Purposeful activities together with
skillful questioning by the teacher can help students understand
relationships among mathematical ideas, as described in the Connections Standard.
||Estimating Scoops (4.6.1)
The teacher presents an
estimation task (estimate the number of scoops of cranberries in a jar)
to the second-grade students and talks about the teaching decisions she
||Discussing Strategies (4.6.2)
The students work in groups to share their ideas and reach a reasoned
consensus about their estimates.
||Estimating Cranberries (4.6.3)
Students estimate the number of cranberries rather than the number of scoops.
