Discuss and record on chart paper, expectations while on the walk. Parent helpers may be required for students needing additional supervision. Make any necessary alterations.
Students form pairs and each receives a clip board and a recording sheet.
Repeat 2 as a whole class until students generally feel confident. Students may then work in pairs to estimate amounts. Discuss the process that students used to estimate the amounts. As skills and confidence develop, allow students to estimate and complete recording sheets independently in pairs. Check roles and cooperation.
