K - 5th Grade Work
||The Investigations unit books are the place to start for lessons. The information below is meant to supplement and extend what you find there. All the lessons here were written from the perspective of someone teaching out of a computer lab as a cluster teacher, where students come and spend 50 minutes a week.
Lessons for kindergarten are structured around filling in outlines
with shapes, free exploration, and creating their own images which
they make into puzzles. If you have regular use of pattern blocks
in your school, all you need to do is go through some very basic
directions on how to move the shapes and give them time to free
explore. I recommend at this level that you get students to choose Don't Save as a norm. If you have access to a color printer the student work will look great on a bulletin board.
- Go through all 10 numbers on the choice Shape of Things.
This is basically an outline which the student fills in with the
available shapes. See the link, Examples of Work.
- Choose the Quick Images activity and run through the
- Have students create their own puzzles using the choices "Create a Puzzle" and "Solve a Puzzle."
- Use the worksheet on Create a Puzzle for Kindergarten.

If students have been exposed to the Kindergarten portion of this
lesson they are ready to start by doing more free exploring with
shapes. Using more commands to flip, turn, minimize and enlarge
to make even a greater variety of designs.
In the second half of the year work begins on quilt squares, where
students create quilt squares, that the computer duplicates into
a quilt pattern.
Second-Graders begin their work by continuing to use the Shapes program.
First they solve more puzzles, these involving more complicated relationships, with a concentration on symmetry.
The second-grade software has more choices, including a mirror activity that lets students create symmetrical images with the basic shapes.
Second-Graders also get their first exposure to Geo-Logo, in the How Far, How Long
unit. In playing the Steps Game students will get introduced to moving the turtle forward and backward. In Maze they will add turning. And in Tina the Turtle they will get exposure to a grid and right angles.
Third-grade is the first exposure to Logo in its full form. The choices of activities
such as Get the Toys and Feed the Turtle are good game to introduce students
to the full commands that navigate the turtle. One should be prepared for frustration from some students who find it difficult transferring the notion of right and left in an environment that they see as up, down and side to side. I usually revisit the How Far Geo Logo just to get everyone comfortable with the four basic commands, FD, BK, RT, and LT.
Lessons in forth-grade use the same game format to get students
interested, but expand how the computer use more commands and exploration
to understanding of grid and quadrant work. This software is called
Geo-Logo Sunken Ships.
Further lessons here begin to ask the students to do more and more free exploring, but at the
same time allow them to construct meaning of geometric forms and problem
solve questions of higher level thinking. This model begins to challenge the students to create the
geometric shapes that they have know in earlier Investigation lessons
and from their earliest exploration of Pattern Blocks.
||The lesson theme for fifth-grade is Picturing Polygons, which as the name suggests uses Logo to allow the student to nor just memorize shapes and their definitions, but construct an understanding of them by making them.
Here you start to really explore the power of Geo-Logo, by creating
very complex programs using both grid coordinates and programs nested
