Thursday, May the FOURTH! (… be with you)

In class: practice applying similarity shortcuts and solving problems involving similar triangles. In 5th period we took our skills to the wilderness and measured the height of various structures near the classroom.


Assignment: 11.3 on p. 562: 1-7, 11-13 and (5th period) Measure the height of something tall using its shadow.

In class: students had time to work on the investigations and problems from 11.2 which deal with similarity shortcuts (AA, SSS, and SAS).

Graded work: students received their volume projects and chapter 10 test back today. The best projects consisted of

* Interesting questions

* Attention to detail

* Excellent real world interpretation and conclusions

* Original diagrams with clear labeling

* Error analysis: how far from the true answer are you? How can you determine the reasonableness of your results?

Assignment: No HW tonight. We will continue with the assignment tomorrow in class.

In class we took notes on proportions and similarity. Two shapes are similar if all their corresponding side lengths are in proportion and all their corresponding angles are congruent.

Assignment: 11.1 on p. 568: 7-15, 18-24

Heads up: We are scheduled to complete SBAC testing soon.

May 11, May 12 — SBAC Math Performance Task (PT)
May 24, May 25 — SBAC Math Computer Adaptive Test (CAT)

For the testing period students will be assign
ed a chromebook and the testing will happen in P-4 (our normal classroom in the portables). Students will need only to bring a pencil/pen. Other resources will be provided: calculators, protractors, paper, etc. Here is a link to the SBAC practice portal if you are interested.

Students should also plan to bring a quiet, non-disruptive activity with them for when they finish. No use of internet devices will be allowed during test days – so cell phones etc. will need to be off and away for the entirety of the testing session. Once testing is complete, working on a puzzle, reading an SSR book, or drawing are the main options.

Let me know if you have any questions about testing.

In class we completed some example proofs and practiced writing proofs of triangle congruence which will be used soon as essential pieces in proving other geometric relationships and the validity of our constructions.

Assignment: Complete "Proofs Practice" packet + mathcounts handout (included)
