There are a number of resources available as sources of great, engaging mathematics tasks.
Michigandeveloped MAISA CCSSI Units (Michigan Association of Intermediate School Administrators – Common Core State Standards Initiative)
Grades: kindergarten through high school
The MAISA project has taken the CCSSM and CCSSELA standards and placed them in units of study for all grades K11. The mathematics units include a unit plan, a detailed model lesson from the unit, one or more formative assessment tasks, and a wealth of other resources. The units are made available through MAISA’s Atlas curriculum management software’s public site.
Jerry Burkhart’s “Creative Math Prompts” provide visual prompts for exploring “What do you wonder?” “What do you know?” See also his “Problems That Never End”.
Jo Boaler and her youcubed team at Stanford University have created and gathered a number of tasks across all grade levels. Since fall 2015, the team has also created a “Week of Inspirational Math” with the idea of kicking off the school year with highly engaging rich mathematics tasks.
Grades: kindergarten through high school
MathHooks.com – intriguing “hooks” for each of the grades 7 and 8 mathematics standards to help teachers kick off lessons through inquiry.

Some of my preservice teachers favorite VM apps
Name of Tool:

Full URL: http://www.glencoe.com/sites/common_assets/mathematics/ebook_assets/vmf/VMFInterface.html 
Why did you select this tool?  I really like this tool because it is very user friendly. You can literally make 100’s of combinations of virtual manipulatives that you would like to use and tailor the site to fit your individualized needs. I also like the way the manipulatives look on the site. They are very realistic looking and I think that the students would enjoy using them. 
How well does it address the target math content?  This site would be great to help with my math lesson on fair share. I think that the picture I took (see below) demonstrates how I could use this site to represent questions on the SmartBoard for my 1^{st} grade students to see. I could present several situations like the one that I have pictured and even allow the students to come up and move the manipulatives themselves. 
Specifically, how would you use this tool to help expose the student’s understanding of the topic?  This site really helps to show students if they can make a fair share or not. The visuals are also big and easy to see. Because I chose to use two ten frames, the students can very easily move the little squares into the correct boxes to see if both people would get a fair share. I could also modify what I have in the picture and show three ten frames and that would help the students be able to make a fair share between three people. This simple task helps to teach the students about dividing numbers by 2 and 3. It is also a great introduction to ½ and 1/3 and even potentially ¼. 
List the ways the tool takes advantage of technology.  – Can be done on the SmartBoard in front of a large group (no need for a document cam with actual manipulatives)
– Kids today love to do things on the computer and this makes learning the concept for them even more fun – There are SO many types of manipulatives on this site. Many teachers do not have access to those materials at their school and the backgrounds on the site may be hard to come up with or draw. 
Name of Tool:
Virtual Polygons for Tessellations 
Full URL:
http://www.mhhe.com/math/ltbmath/bennett_nelson8e/VMK.html?initManip=polyTess 
Why did you select this tool?  I selected this tool because my teacher that I am observing just recently did a lesson on tessellations and wanted to incorporate some technology into her lesson. Unfortunately, there are a lot of ineffective virtual tessellation websites out there. It took me a while to find one I liked and that was actually helpful. This website also has an informative instructional video to help teachers know how to use it correctly. 
How well does it address the target math content?  This website addresses the content (tessellations) pretty well, but I think it could have been a little more detailed with more color choices and it could potentially be more user friendly. 
Specifically, how would you use this tool to help expose the student’s understanding of the topic?  This tool would make it easier to see teacher created tessellations as a whole group and would also allow the students to see the stepbystep of creating a tessellation as the teacher makes it! 
List the ways the tool takes advantage of technology.  This tool is great because it really uses the advances in technology to its advantage. Creating a tessellation by hand with literal manipulatives, can take time and it can be difficult to make extremely accurate. This program helps students create tessellations with several shapes at a fairly rapid pace and overall makes it a similar process.
