# 2nd Grade Geometry Skills Prior Standards Implementation

## Geometry

Identify, build, draw, and compare two- and three-dimensional geometric figures.
2.3.1 a
1. 2 and 3D shapes Activities - identify and investigate two-dimensional and three-dimensional shapes
2. 2D shapes - identify and compare these shapes
3. Create your own pattern - drag shapes to create a pattern ( Instructions on how to use this page in your classroom )
4. Geo Cleo - take a look at how to describe three-dimensional shapes )
5. Pattern Detectives - identify and extend patterns in a variety of settings Audio is used to assist non-readers.
6. Point Out the View - a ten level activity from PBS Kids, students must show what 2-D view each of four viewers would see when looking at a stack of blocks
7. Polygons and Non-Polygons - drag polygons into one bin and anything that is not a polygon into another bin
8. Solid Pattern Pieces - name the different faces of solid figures to make objects using a pattern
Describe characteristics and parts of two- and three-dimensional geometric figures.
2.3.1 b
1. Anglemania - ( 3-5 ) describe triangles using appropriate geometric vocabulary ( decide if this is appropriate for your second grade students )
2. Mr. Mumble - take a look at how to describe two-dimensional shapes
Identify shapes that have line symmetry.
2.3.1 c
1. Ask Hannah - Students describe symmetry in two-dimensional shapes.
2. Line Symmetry - many activities here
3. Lines of Symmetry - drag the shapes that have lines of symmetry into one bin and those that do not into the other bin
4. Symmetry Lesson - and interactive quiz
Investigate and predict the results of combining and taking apart two- and three-dimensional geometric figures.
2.3.1 d
1. Point Out the View - a ten level activity from PBS Kids, students must show what 2-D view each of four viewers would see when looking at a stack of blocks
2. Solid Pattern Pieces - name the different faces of solid figures to make objects using a pattern
Identify the position of a whole number on the number line.
2.3.2 a
1. Estimate numbers on a number line - after students make their estimate you reveal the answer and display a new problem.
Illustrate flips, slides, and turns using concrete objects and pictures.
2.3.3 a
1. Flipping Monsters - Can you make all the Space Monsters face to the right? You must turn two monsters at a time. They must be next to each other.
2. Icy Flips, Slides, and Turns - Use this interactive site from Harcourt to review the three concepts.
3. Math Manipulatives: Flips, Slides, and Turns - select a shape and then apply one of the transformations to it.
4. Ten Question Worksheet - print for your students to practice flips, slides, and turns
5. Transformations - Interactive sites

Practice Tests
Interactive Practice Games
1. Number Gym - This software company provides games as demonstration copies of their commercial product. All games are labeled "Demonstration" but are working copies and can be used by your students.
Daily Questions
1. Daily Questions - to be given three times per week to serve as a ten to fifteen minute (approximate) review of practice test items and critical thinking (a 134 page document)
1. Measurement - Measurement - Graphs and Data
National Library of Virtual Manipulatives
