Learning Activity

Learning Activity

During whole group instruction, students will:
  1. Take notes from the SMART Board, follow along as the teacher works example problems, working out the problems on their slates, and then work guided practice questions on reading and writing ratios and generating equal ratios. Students will use colored tiles to understand ratios.
  2. Take notes from the SMART Board, follow along as the teacher works example problems, working out the problems on their slates, and then work guided practice questions on writing percents for a given situation and creating situations for given percents.  The students will work with a partner to create situations for given percents and then present to the class.
  3. Take notes from the SMART Board, follow along as the teacher works example problems, working out the problems on their slates, and then work guided practice questions on writing numbers as fractions, decimals and percents.
  4. Take notes from the SMART Board, follow along as the teacher works example problems, working out the problems on their slates, and then work guided practice questions on finding the given percent of a whole number.
  5. Take notes  from the SMART Board, follow along as the teacher works example problems, working out the problems on their slates, and then work guided practice questions on solving problems, making a table and looking for a pattern.
During independent work time, students will complete the:
  1. 16-1 Understanding Ratios Quick Check and Practice worksheet.
  2. 16-2 Understanding Percent Quick Check and Practice worksheet.
  3. 16-3 Percents, Fractions, and Decimals Check and Practice worksheet.
  4. 16-4, Finding Percent of a Whole Number Quick Check and Practice worksheet. 
  5. 16-5, Problem Solving: Make a Table and Look for a Pattern Quick Check and Practice worksheet

At the end of each unit, the students will use their computers to play a review game over that topic by going to the Mind Point Quiz Bowl icon on their computer.

Instructional Method

During whole group instruction, the teacher will:
  1. Display the Visual Learning Animations CD-ROM on the SMART Board, use prepared lesson materials to discuss, model examples and provide guided practice problems, providing assistance and feedback as needed on reading and writing ratios and generating equal ratios. Students will use colored tiles to understand ratios. .
  2. Display the Visual Learning Animations CD-ROM on the SMART Board, use prepared lesson materials to discuss, model examples and provide guided practice problems, providing assistance and feedback as needed on writing percents for a given situation and creating situations for given percents.  The teacher will put the class into partners and give percents to each set of partners and have them to write a story problem for that percent and then give guidance as needed during  group work and their presentation.
  3. Display the Visual Learning Animations CD-ROM on the SMART Board, use prepared lesson materials to discuss, model examples and provide guided practice problems, providing assistance and feedback as needed on writing numbers as fractions, decimals and percents.
  4. Display the Visual Learning Animations CD-ROM on the SMART Board, use prepared lesson materials to discuss, model examples and provide guided practice problems, providing assistance and feedback as needed on finding the given percent of a whole number.
  5. Display the Visual Learning Animations CD-ROM on the SMART Board, use prepared lesson materials to discuss, model examples and provide guided practice problems, providing assistance and feedback as needed on solving problems, making a table and looking for a pattern.
