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.

Through this four part lesson students develop an understanding of the relationship between area and perimeter. The lesson involves students making human rectangles, exploring geoboard connections, playing perimeter war, and playing Square Off from Calculation Nation. The lesson plan includes all data collection worksheets, games pieces, link to Calculation Nation, extension and assessment ideas.

This 40-day final module of the year offers students intensive practice with word problems, as well as hands-on investigation experiences with geometry and perimeter.  The module begins with solving one- and two-step word problems based on a variety of topics studied throughout the year, using all four operations.  Next students explore geometry.  Students tessellate to bridge geometry experience with the study of perimeter.  Line plots, familiar from Module 6, help students draw conclusions about perimeter and area measurements.  Students solve word problems involving area and perimeter using all four operations.  The module concludes with a set of engaging lessons that briefly review the fundamental Grade 3 concepts of fractions, multiplication, and division.

Este módulo final del año de 40 días ofrece a los estudiantes una práctica intensiva con problemas de palabras, así como experiencias prácticas de investigación con geometría y perímetro. El módulo comienza con la resolución de problemas de palabras de uno y dos pasos basados ​​en una variedad de temas estudiados durante todo el año, utilizando las cuatro operaciones. A continuación, los estudiantes exploran la geometría. Estudiantes Tessellate para la experiencia de la geometría de puente con el estudio del perímetro. Las parcelas de línea, familiares del Módulo 6, ayudan a los estudiantes a sacar conclusiones sobre las mediciones de perímetro y área. Los estudiantes resuelven problemas de palabras que involucran área y perímetro utilizando las cuatro operaciones. El módulo concluye con un conjunto de lecciones atractivas que revisan brevemente los conceptos fundamentales de grado 3 de fracciones, multiplicación y división.

In this lesson, students deepen their understanding of the measurement of plane and solid shapes and use this understanding to solve problems. Students also identify and describe the properties of two-dimensional figures. Students are challenged to set a table for 22 using one unit lengths of paper (each unit length represents one student sitting at the table). They are asked to pretend that they all want to sit together for a dinner, and the table has to be rectangular. They must figure out what the table will look like if it must be rectangular and if everybody must sit at the table. They must determine what's the biggest table going to look like where everybody sits, and what's the smallest table going to look like where everybody sits. Students work to conceptually figure out relationships between perimeter and area in a creative and interactive way. They brainstorm ideas in groups, discuss as a class to determine the best options, and then physically set the two tables using strips of paper that represent "one unit" in length per person.
