The Center for Applied Special Technology (CAST) applied UDL guidelines to the design of these puzzles that can be used at different grade levels and can be solved in many ways. Here is what they say about the features of these UDL math puzzles.

"All iSolveIt puzzles are designed with the following features:

• The puzzle sets do not connect to any specific content in the math curriculum, so they can be used throughout a yearlong curriculum.
• There are several different ways to solve the puzzles, and many puzzles have more than one solution.
• Each puzzle format has multiple levels of complexity. Students can select puzzles that they find challenging and do not have to follow any specific path through the puzzle set.
• Each puzzle format has the potential for unlimited puzzles at different levels of difficulty, and puzzles also can be solved multiple times. This ensures that the puzzles can easily be used throughout the school year.
• All puzzle formats include embedded supports designed for the specific format and based on the principles of UDL. The supports will aid reasoning skills but do not reveal the solution."

Appropriate for any pre-school setting, Equals PreK from ablenet curriculum provides instruction and materials for teaching foundational skills of counting, subitizing, cardinality, 1:1 correspondence, color and shape identification, math vocabulary, matching and sorting by attributes, joining and separating to construct sets, basic patterns, building shapes and designs with 2-D shapes, comparisons of amounts and length, one more and one less, and beginning quantitative and positional concepts.

Discover math tools and resources that can support learning for learners with disabilities and their classmates. A searchable database is included on this site with the ability to select IDEA disability categories, grade levels, operating systems and the Math CCSS.   

"Now you can do math without holding a pencil. Panther Math Paper  app integrated the principle of Universal Design into an elegant interface that allows people to work independently on "digital paper". Math Paper offers the foundations to learn simple arithmetic, and the power to do complicated equations."

Thank you to Colleen King of Math Playground who offers these great games for free online and on mobile devices. Take a look at the other great games she has recently created.

 "This video series introduces key Common Core concepts in 6th grade mathematics. Each video focuses on building conceptual understanding of a topic, so that students understand the “how” and “why” behind mathematical problem solving. 

Use these videos with your students as topical introductions to topics including integers, the concept of ratios, unit rates, percent, and division with fractions."

PBS Learning Media has put together a set of videos to support learners in math. Take a look around and you will discover brand new, original content from PBS including Peg + Cat (Pre-K) and the PBS Math Club (Grades 6-8)!
