SumBlox: explore number relationships through visual/kinesthetic play

** This is not a sponsored post, I’m just super excited about this product and can’t wait to see what our students do with it!

What it is: Why yes, this is a technology blog. But no, this manipulative is not a technology product. I’m writing about SumBlox here anyway because technology led to the happy discovery of SumBlox and is a great reminder of why it is important to be a connected educator! I learned about SumBlox just a few weeks ago on Twitter as a share from ISTE from @michellek107 and @sumblox. This also isn’t a free tool (like I normally share), but I’m already so impressed by the brilliance of this tool, that I’m sharing it anyway!

SumBlox are a wooden block set of numbers 1-10. What makes those blocks and numbers super amazing: each block size corresponds to the number that it represents. (1 being the smallest and 10 the biggest). Even more super amazing, when the blocks are stacked, they represent the equivalent number. For example, when the 2 and 3 blocks are stacked, they are the same height as a 5 block! GENIUS!! These blocks are a visual and kinesthetic representation of our base-ten number system.

I purchased the Educational Set for our classrooms which comes with 100 solid hardwood blocks including: Thirty 1 blocks; twelve 2 blocks; eight each of the 3, 4, 5, 6, 7, 8, and 9 blocks; two 10 blocks and four teaching manuals. The purchase was right around the $300 mark with free shipping and a 10% discount with the code “sumfun.”

How to use SumBlox in the classroom: These blocks allow students to visually represent and discover math relationships. Students can stack blocks to explore and visualize addition equations, if the stacks are the same height, they also have equivalent values. Students can stack multiples of a number to represent abstract math concepts like multiplication grouping or addens of ten. Students can also explore the concept of fractions and of the mathematics behind adding fractions with different denominators by stacking and scaling fractions. SumBlox also are a fantastic introduction to algebra concepts.

The educational set comes with 4 guides that lead you (the teacher) through exercises and lessons to do with your students. While these are extremely well done, because we are inquiry based, my excitement comes in seeing how students will explore these independently first. I’m excited to see students discover the number/size relationships and number patterns.

At Anastasis, we have a 1:1 iPad program. I anticipate that students will use these blocks for stop-motion animation projects as they explore (iMotion HD is the app they use), capture their discoveries of number relationships in their eportfolio (we use Evernote), and even in Explain Everything videos.

Tips: If you are an administrator purchasing these for your school, go ahead and purchase a few of the educator kits. I only purchased one and am already going back to order one for each classroom. These are going to be popular!

Interactives Geometry 3D Shapes

What it is: I ran across this site yesterday as I was searching for a Geometry site for a teacher. Interactives Geometry 3D Shapes is a great website for students to learn about 3D shapes, surface area and volume, Euler’s theorem, and platonic solids. Each section gives students an interactive environment where they can manipulate 3D objects as they learn. In the surface and area section, students can learn how to calculate area of a 3D object and then have an interactive space to practice calculating the area of 3D objects. At the end of the site there is a place where students can put their knowledge to the test and apply what they have learned. This is an outstanding alternative to learning from a text book. The Interactives site gives students what a text book can’t, interaction with 3D shapes and the ability to rotate and manipulate the shapes. Throughout the site, math words are highlighted in red, students can click on these words and are taken to a glossary that defines the word for them.

How to integrate Interactives Geometry 3D Shapes into the classroom: Use the Interactives Geometry 3D Shape site to introduce 3D shapes, area, Euler’s Theorem, and platonic solids to your students. This is a great way for your students to learn geometry, especially 3D geometry, in an environment where they can interact with and manipulate 3D shapes. This site could be used with a projector, interactive whiteboard, as a math center in the one computer classroom, or individually in a lab setting. Use the interactive portions with an interactive whiteboard to manipulate shapes for students to see as you are teaching new concepts about 3D shapes. This would be a wonderful site to point your students to for geometry homwork help, students can use it to model and define concepts they may find difficult as they work.

Tips: The Test Your Skills section gives students 15 problems to complete that are accompanied by photos, illustrations, or animations. I wish my geometry tests looked like this! I am such a visual person, I think I would have been so much more successful.

Library of Virtual Manipulatives

November 7, 2007November 8, 2007Kelly TenkelyLeave a Comment2031 views

What it is: The Library of Virtual Manipulatives is a library of interactive, web-based virtual manipulatives or concept tutorials for mathematics instruction (K-12 emphasis). Manipulatives are for students in grades kindergarten through twelve and include hundreds of manipulative tools in the areas of Numbers and Operations, Algebra, Geometry, Measurement, Data Analysis, and Probability. Manipulatives include interactive base 10 blocks, money, pattern blocks, tangrams, geoboards, clocks, and bar/pie charts just to name a few.

How to integrate Virtual Manipulatives into the classroom: Virtual Manipulatives can be used in place of actual manipulatives in math class. There are many benefits to the virtual version of manipulatives. First, math manipulatives can be expensive, especially when a class set is required. The Virtual Manipulatives are completely free to use. Math manipulatives can take up a lot of storage space. The Virtual Manipulatives are accessible quickly and easily and there is never any need for set up or clean up. The Virtual Manipulatives never wear out and need to be replaced. In the one or two computer classroom, set up a Virtual Manipulative center where students can stop by individually or in groups and work with the manipulatives. Use a projector cart for whole class instruction. Virtual Manipulatives are ideal for the 1 to 1 computing environment.

Tips: Share the Virtual Manipulative site with parents. The manipulatives are great for use at home while students are completing math homework!
