3-5
Investigate
fractional parts of the whole and use translations, reflections, rotations, and
line symmetry to make four-part quilt squares.
3-5
Students create a quilt using the three transformations and investigate the ways shapes can be colored to show one-half and one-fourth. They locate lines of symmetry and create a set of directions for making their quilt block.
3-5
This lesson encourages students to explore the geometric transformation
of rotation, reflection and translation more fully. Students create a
design then, using flips, turns, and slides, make a 4-part paper
"mini-quilt" square with that design as the basis. This experience
focuses students’ attention on both the changes produced by the
geometric transformations and on line symmetry.
3-5
Students begin their study of growing patterns by making linear
patterns with pattern block shapes using several pattern cores. They
extend a partner’s pattern and find the missing element in a pattern.
3-5
This lesson encourages students to explore the geometric transformation
of rotation. Students create a design then, using turns, make a
four‑part paper "mini-quilt" with that design as the basis. While the
formal term is rotation, the more informal turn is used at this grade
band. The experience focuses students’ attention on the changes the
geometric transformations make in a student-designed quilt square.
3-5
This lesson builds on the previous two lessons and encourages students to explore the geometric transformations of reflections and translations. Students create a design. Then, using flips and slides, students make a four-part paper "mini-quilt." While the formal terms are
reflection and
translation, the more informal terms
slide and
flip are used at this stage. The experience focuses students’ attention on the changes these geometric transformations make in a student-designed quilt square.
3-5
Students create designs and describe them to a classmate, using fractional and geometric terms. This lesson provides a context for using the following vocabulary terms: horizontal, vertical, square, rectangle, triangle, diagonal, one-half, and one-fourth.
3-5
Students investigate the ways shapes can be divided into equal pieces
with one or two cuts. The lesson provides a review of the following vocabulary
terms:
square, triangle, and rectangle; congruent, one-half, and one-fourth.
The other lessons in this unit build on this introductory lesson.
