HRCE Rubrics for N03, N04, N05 - These rubrics can be used for a variety of purposes such as a resource to create learning goals, a tool for student self assessment and on-going, formative assessment, creating report card comments, summative assessment of achievement, and/or as a support in giving descriptive feedback to students.
Online math tools: Grids, dot grids, expression mats, algebra tiles, base 10 blocks, number lines,
Additional Resources and Activities for N03 (percent):
*Updated December 2024* Percent of a Number Google Slides (English, French): In this activity, students shade the a given percentage of a shape and then explain their reasoning. This can be used with technology or printed for each student.
How Many Times Will A Case of Paper Jam?- A company makes copy paper that it claims to be “99.99% jam free." How many paper jams would you expect to have happen in one ream? Here is a link to a Google Slides to explore this question.
Tarsia Puzzle - Fractions, Decimals and Percents from Engaging Math - Students have cards that have either an answer or question on the edge. They then have to match up the edges that have the pairs of questions and answers and eventually it will make a shape. In this case the activity is matching up different representations of the same number (Decimals, Percents and Fractions N03.05, N03.06 and N03.07). These puzzles can be created on your own using the free Tarsia software.
What do you know about percent? Ask students what they know about 35% Can they explain their thinking using a variety of different methods? (words, pictures, graphs, etc)
Relating Fractions, Decimals and Percents Review Desmos Activity - A self checking Desmos review with 28 questions.
Additional Resources and Activities for N04, N05 (ratio and rate):
Comparing Strategies for Proportion Problems - This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. Click here for the teacher lesson plan and student pages. Click here for presentation slides for this lesson. (N05)
Super Bear - This is a three act task from Dan Meyer exploring the relationship between the different sizes of gummy bears. The lesson is laid out in 3 parts with accompanying videos to use as students problem solve.
Using the Internet to Create Proportion Problems from Jon Orr - Let student create their own problem about proportion and rates using The Internet in Real-Time website. Here was my example of a proportion problem: “If there are 48818 apps downloaded in a minute from Apple, how many in one day?”
How Fast is Usain Bolt Running? - Stop the video after 100m, 200m and let students guess and then revise their guess for how long it will take him to finish. See how close they are. They can then calculate speed.
World's Biggest Tire Turns 50 Years Old - The tire stands 24 metres, or 80 feet, high and weighs 10 metric tonnes or 12 U.S. tons. A car would have to be 60 metres or 200 feet tall to handle it. It has stood alongside Interstate 94 since 1965, a year after it debuted at the New York World's Fair. Ask students to estimate the size of the tire and then the ratio of it to a normal car tire. What would the size of the car that would use this tire be?
