Extensions for Math Investigations: Grade 1 – 3rd 9 Weeks
These activities are intended to “extend” the lesson, not replace, for those students that
might benefit from further study.
Quilt Squares and Block Towns
Investigation 1
2-D Shapes and
Patterns
Investigation 2
Comparing and
Constructing 3-D
Shapes
Investigation 3
Building a Block
Town
 Introduce all of the tools in the “Shapes” software
 Students create bar graphs to indicate the number of each shape they used for a
Pattern Block Fill-in on a student sheet. (provide graph paper for cutting into strips
for bar graph)
Students show a minimum of 3 different ways to fill in one Pattern Block Fill-in
Students read or listen to The Greedy Triangle by Burns and draw pictures showing
how one shape becomes another as a new side is added; Students write the name of
each shape below their drawing.
 Play Mystery Objects in class using shape, size, and texture
Students copy cube things and then orally describe each to a partner using
appropriate mathematical terms such as height, width, etc.
Student create cube things following written rather than visual directions (example:
create a cube that is 4 units tall, 3 units wide and 2 units deep)
 Extensions on page 105
Students read or listen to Roxaboxen, or other book about shapes, and then create the
elements in the story using geoblocks
 Extensions on pages: 111, 118 ,(be sure students describe some of the shapes of the
town buildings in their story), 126
