This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

Unit Title: Dream Garden MeasurementsAuthor: Melissa WimmlerSchool: Discovery Charter School, Columbus School DistrictGrade Level: 2nd GradeContent Area(s): Math, Environmental ScienceContext: Our governance council is working on a school wide project to improve the lawn space in front of our school and create our dream garden. During this six-lesson unit the second-grade students estimated and accurately measured objects in the space and perimeter. The students calculated the area of the space and used square units to plan spaces and garden beds.

In this unit, students use online pan balances to study equality, order of operations, numerical and variable expressions, and other key algebraic concepts. Lessons focus on balancing shapes to study equality and equivalence; balancing algebraic understanding, to explore simplifying expressions; and balancing algebra, to determine if algebraic expressions are equal.

Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction.  The module begins with plenty of hands-on experience using a variety of tools to build practical measurement skills and conceptual understanding of metric and time units.  Estimation naturally surfaces through application; this transitions students into rounding.  In the module’s final topics students round to assess whether or not their solutions to problems solved using the standard algorithms are reasonable.

El módulo 2 utiliza el valor del lugar para unificar la medición, las habilidades de redondeo y los algoritmos estándar para la adición y la resta. El módulo comienza con mucha experiencia práctica utilizando una variedad de herramientas para desarrollar habilidades prácticas de medición y comprensión conceptual de las unidades métricas y de tiempo. La estimación surge naturalmente a través de la aplicación; Esto hace transición a los estudiantes al redondeo. En los temas finales del módulo, los estudiantes redondean para evaluar si sus soluciones a los problemas resueltos utilizando los algoritmos estándar son razonables.

This is a Interactive PowerPoint Presentation on Weight vs. Mass and how they differ.  It shows students a definition of each as well as giving them the hands-on ability to manipulate pictures via a whiteboard or any kind of screen.  Students also have an assessment at the end to see what information they have gathered thru the data presented.
