Day 65: Percentages Study Guide

6th Grade Math Standards: Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. a. Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios. b. Solve unit rate problems, including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then, at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed? c. Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent. d. Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.

Objective: Convert between percentages, decimals, and fractions; order percentages, decimals and fractions; find the part given whole; find the whole given part; use percentages to solve real world problems

Agenda:

1. Visual Pattern #27
2. QSSQ 
3. Skipped reviewing homework and opted instead for my own couple of problems I made up on the spot. 
4. Study Guide 
5. Stations: 99 Restaurant Tip, other practice material 

Assessment: Students worked in groups on the stations and I sat in on two specific stations. The 99 restaurant station (which challenged them) and then a percent problem that forced students to consider the thousandths place as it was converted to a decimal were the places I put myself. The study guide was done individually or in partners and then reviewed for all students.

Glass Half-Full: I think that problems escalated in difficulty as the days progressed in this unit. Each day logically built on the preceding day and at the same time all students were challenged without being pushed past the point of giving up. Kind of the goal of teaching, right?

Regrets: Some of the station stuff was impossible to review because of the pace of the group activities and my availability and necessary instruction at the two stations that I needed to visit.
