Grade 7 Mathematics
For Galveston ISD on 3/11/2015
7.5 PROPORTIONALITY
The student applies mathematical process standards to use geometry to describe or solve problems involving
proportional relationships. The student is expected to:
Readiness Standards
7.5(C)
solve mathematical and real-world problems involving similar shape and scale drawings
Supporting Standards
7.5(A) generalize the critical attributes of similarity, including ratios within and between similar shapes
7.5(B) describe p as the ratio of the circumference of a circle to its diameter
7.6 PROPORTIONALITY
The student applies mathematical process standards to use probability and statistics to describe or solve problems
involving proportional relationships. The student is expected to:
Readiness Standards
7.6(G) solve problems using data represented in bar graphs, dot plots, and circle graphs, including part-to-whole and
part-to-part comparisons and equivalents
7.6(H) solve problems using qualitative and quantitative predictions and comparisons from simple experiments
7.6(I) determine experimental and theoretical probabilities related to simple and compound events using data and
sample spaces
Supporting Standards
7.6(A)
7.6(C)
7.6(D)
7.6(E)
represent sample spaces for simple and compound events using lists and tree diagrams
make predictions and determine solutions using experimental data for simple and compound events
make predictions and determine solutions using theoretical probability for simple and compound events
find the probabilities of a simple event and its complement and describe the relationship between the two
Multiple representations (symbols, diagrams, graphs, and language as appropriate) to help them remember:
SEs to reinforce

Now What? Learning Loopback Plan (connections in upcoming units, add to review, warm-ups, etc.)

Teacher prepares a set of dominoes with academic vocabulary terms (1 set per group)
Students are placed in groups of four.
Vocabulary dominos are placed face down and scrambled.
Each student is given six dominoes.
One domino is placed in the center to begin the game.
Each player takes a turn matching one of their vocabulary dominos with one on the
board explaining how the two terms are related to each other.
Students continue to use the six dominoes they were given at the start of the game,
making connections as players take turns.
Should a student not be able to make a connection, he/she draws another vocabulary
domino and tries to make that one connect.
The first person to place all of their vocabulary dominoes on the board wins!

Trashcan Basketball Review TEKS Knowledge & Skills
7.5 & 7.6 Proportionality (Geometry, Probabilty, and Statistics)

Student are provided a set of review items aligned to focus Knowledge
and Skills Statements

Teacher sorts questions based on complexity:
o Free Throws (1 point – easiest questions)
o Lay Ups (2 points – medium questions)
o 3 Pointers (3 points – complex questions)

Teacher organizes students into pairs

Pairs play trashcan basketball!
1. SET UP THE SHOT:
 Pairs choose a question and cut it out of their test handout
 Pairs answer question cooperatively, showing their work
2. CHECK THE SCORE:
 Pairs consult the teacher’s "playbook" (answer key) to determine
if their answer is correct
3. FOLLOW THROUGH: (If you missed – self correct)
 Explain why the original answer was incorrect on the back
 Explain why the correct answer IS the appropriate response on
the back.
 Teacher verify.
4. TAKE THE SHOT:
 Pairs take turns "shooting" the questions into the appropriate
“basket” (3 pointer, 2 pointer, 1 point free throw)
 Students keep shooting until they make it
