Here is a snapshot of some math resources you should know about. What I really like about these resources is that they have resources for many grade levels. So please check them out. You may find something you can use in your classroom next week.
The first resource I share with you is Illuminations by NCTM ~ Resources for Teaching Math (K-HS).
If you visit this site you can search for activities based on a grade range of activities or the following math strands: numbers & operations, algebra, geometry, measurement, and data analysis & probability.
Once you sort by grade band, you can skim and scan the activities to find an activity that fits your goals and objectives.
Another resource I wanted to share is Inside Mathematics (K-HS). If you click in the box in the upper right hand corner, shortcuts by grade or strand, you could narrow your search to what would be most beneficial to you and your students.
Here you can see I searched for numbers and operations in base ten. Then I clicked on second and third grade. Here you can find different problems of the month and performance assessment tasks. Use these activities to encourage math talk in your classroom. Adapt the activities to fit the needs of your students.
There are video resources available at Inside Math that can be helpful as well to the teaching of mathematics.
The final resource I am going to share is K-5 Math Resources. You can search for activities by grade level band and strand: number, geometry, and measurement/data. You may some free resources here.
As you can see, I searched third grade activities in the number strand. The standard comes up along with possible activities. If you click the link, you can print off a PDF to use with your students.
Here is another example if I searched second grade activities in the measurement and data activities.
As with any resource, you have to evaluate the activities based on the needs of your students and the goals you hope to accomplish.
I would love to hear what math resources you use for your students. Thanks for stopping by, and I hope you can add some ideas you found on these sites to your math toolbox.
