About this resource

The Measurement: Investigation is a vital empowering teaching resource designed for educators in public schools and homeschooling. This product skillfully blends into a broad variety of curriculum settings, serving Kindergarten through Grade 3 students, with its focus on enhancing the understanding of math and measurements.

This material is composed of an engaging 3-page booklet that offers three insightful measuring length activities.

  • Math Investigation: The first activity prompts learners to actively investigate whether they are wider than they are long. This exercise utilizes physical dimensions to foster enhanced comprehension about length versus width.

  • Practical Measuring Tasks: Subsequent activities allow students to gain practical knowledge by measuring different lengths of strings and various objects in both centimetres and millimetres. These tasks enhance their hands-on experience, giving them an opportunity to hone their skills while minimizing abstraction often associated with mathematical concepts.

The design of the Measurement: Investigation resource imparts flexibility for all types of teaching methods like using it in whole-group instruction or small-group learning sessions. It’s even an ideal tool for reinforcement practice as homework assignments that give children active engagement outside the school setting.

A key feature worth noting about this educational tool is its layout - organized across three pages within a PDF file type format. This ensures easy access wherever you may be working from - be it at school or home.

In sum, this innovative resource illuminates measurement concepts while making math engaging and fun to learn through immersive exploratory tasks integrating object observation and tactile interaction.
