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.

This lesson explores elapsed time through the use of timelines. Students will use timelines to mark start times and end times of given activities, and will interpret the timelines to understand how to calculate elapsed time.  With the exception of the Timeline Activity Sheet, you will want to make sure that each student has one copy of each activity sheet. Make multiple copies of the Timeline Activity Sheet so that each student can have at least 3 copies.

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.

In this 5-lesson multi-media unit, students will explore various real-world applications of different forms of measurement, including time and distance. They will make estimations and calculations. Throughout the unit, students will be using online resources to familiarize themselves with coral reefs, the nation of Belize, and to plan a pretend scuba diving trip. Activity sheets (pdf), links to online resources, assessment options and other commentary are provided.

This is a telling time game that has multiple levels.  It has a practice session that shows the students how to play the game.  Then it begins the game with level 1 which is telling time to the hour.  It goes up 4 levels. Students are asked to choose an analog or digit clock.  They are given a time, and then they are asked to move the clock to show that time.  I would use this game to reinforce what students have already learned about telling time.  It would be good for students who are struggling, or for students that are ready to move to the next level.
