MATH TOOLS NEWSLETTER - May 28, 2013 - No. 120

Ever wondered what the Math Forum is all about? What makes 
us passionate? What IGNITES us? Now you can find out! See 
how well we do with 20 PowerPoint slides advancing every 
15 seconds, whether we're ready or not.

Our focus on sense-making and communication in our Problem 
Solving Activity Series is so important, we wrote a book 
about it! Powerful Problem Solving: Activities for 
Sense-Making with the Mathematical Practices, authored by 
Max Ray, gathers what we've learned about helping students 
become proficient problem solvers, focused through the 
lens of the Common Core Standards for Mathematical Practices.

Tool: Fraction Model I
NCTM: Illuminations
This tool explores several representations for fractions 
using adjustable numerators and denominators. You can see 
decimal and percent equivalents, as well as a model that 
represents the fraction. This applet restricts the range 
of the numerator from 0 to 20, and the denominator is 
limited to benchmark values of 1, 2, 4, 5, 8, 10 and 20.

Tool: Teacher's Assistant Lite
Lesson Portal LLC
Teacher's Assistant Lite allows teachers to keep track 
of student actions, behavior, infractions, and achievements 
in the classroom. The lite version allows you to use the 
app with 5 students with up to 3 actions per student. 

Tool: Teacher's Assistant Pro
Lesson Portal LLC
Teacher's Assistant Pro allows teachers to keep track of 
student actions, behaviors, and achievements in the 
classroom. Communicate with parents and administration 
by documenting student habits and behaviors and sending 
reports via email, text or making a call right from 
your iPhone.

Tool: Adaptive Learning Tool for Maths
The ToKToL online adaptive learning platform contains 
a large (2000) set of maths questions and associated 
explanatory texts. Questions are selected to adjust to 
the ability of the student so that when students get 
several questions wrong, questions will tend to become 
easier. A teacher platform (please request an account) 
allows teachers to track progress and performance of 
students on individual assignments with detailed feedback.

Activity: Printable compass / straightedge construction
   worksheets - Math Open Reference
John Page
A web page that contains a list of 35 printable worksheets
for compass and straightedge constructions. Each printable
sheet has 2 or 3 problems and links back to the pages
interactively explaining the constructions needed. Each
sheet has a space for student name.

Technology PoW: Building a House
Suzanne Alejandre
Use a Java applet from the Freudenthal Institute to 
help find the largest number of cubes and the smallest 
number of cubes to make the house pictured in the problem.

Technology PoW: Traffic Jam
Suzanne Alejandre
There are eleven stepping stones and ten people. On the 
five lefthand stones, facing the center, stand five of the 
people. The other five people stand on the five righthand 
stones, also facing the center. The center stone is not 
occupied. Find the fewest number of moves for the ten people 
to end up on the opposite side from where they started.
