National Library of Virtual Manipulatives

National Library of Virtual Manipulatives:
Wendy showed me this website today - it has virtual math manipulatives (perfect for smart boards!) sorted by grade level and topic.  It was really helpful with visualizing shading in fractions of geometric areas.

Bedtime Math

I heard a segment on NPR that spoke about a mother who gave her children mental (or not) math problems at bedtime each night. Here is the link to the NPR segment: http://www.npr.org/templates/archives/archive.php?thingId=157644780
The math problems help her children focus and settle down. When her friends showed interest in sharing the same practice with their children, she (Laura Overdeck) created a website. Here is the link to the Bedtime Math website: http://bedtimemathproblem.org/about-us/how-we-started/
This is aimed for young and older children and there are two or three levels presented each day. I might implement this each day with my class as a morning warm-up. Given the variations, Ms. Overdeck presents, I can differentiate for skill levels. Another possibility is to sell this idea to parents, but I suspect that children with enriching home environments would be involved, but children with little academic support at home would not. I want to reach all my students.

Partitive vs Quotative word problems

Is anyone else having a hard time writing the word problems for problem set 3 pg 306? I understand the concept, but for some reason it has been really difficult to come up with a word problem that works. I did numbers 1 & 4. For number 4, for a Quotative problem, I used the following: Brenda walks 3 miles every day. Brenda has walked a total of 21 miles. How many days has Brenda walked? 21 miles/3 miles per day= 7 days. And for partitive I came up with Brenda needs to walk 30 miles in 10 days. How many miles will Brenda need to walk per day in order to reach her goal? 30 miles/10 days=3 miles per day. I had originally written the first problem to represent a Quotative problem but the quotient was expressed as a complex noun (objects per group) so I revised my answer. Is this correct now??

Explore Lessons | LearnZillion

Explore Lessons | LearnZillion: Teachers around the country are building a bank of common core lessons - sorted by topic and grade level.  So far, they have math lessons posted for grades 3-12 and they are sorted by domains and standards.  LearnZillion started at the E.L. Haynes Public Charter School - it combines video lessons, assessments and progress reporting.  You can add lessons by standard, assign them for homework, and be notified of your students' results after they take a post homework quiz.  You can also differentiate instruction for students who are above or below grade level.
