Solve Me Puzzles - Play or Create Math Puzzles
Solve Me Puzzles is a free site provided by the nonprofit Education Development Center. The site offers free math puzzles for students to play and templates for teachers to use to create math puzzles. Solve Me Puzzles features three basic puzzle types. The Who Am I? puzzles feature a little robot character that students identify by correctly solving word problems like "my value is even, my value is greater than six, my value is less than ten." The Mystery Grid puzzles have students slide numbers into a grid to correctly complete the patterns that are started in the grid presented to them.

Visit solveme.edc.org to play SolveMe Mobiles, SolveMe Who Am I?, and SolveMe MysteryGrid.

Number Frames
Overview Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities. This helps primary students move away from one-by-one counting toward more efficient ways of counting and computing.

Math language can cause problems for many English language learners. Math word problems are especially difficult because the language around the word problem can often times be a challenge. As a very basic example, look at the many synonyms for "DECREASE": subtract, take away from, lowered by, reduce, minus, etc. Then there are the NON-MATH words in the problems. Look at this basic math problem for elementary school: Five boys and three girls went on a field trip.

What is the Golden Ratio? – Math Memoirs – Medium
The Golden Ratio has been heralded as the most beautiful ratio in art and architecture for centuries. From the Parthenon to Salvador Dali’s The Sacrament of the Last Supper the Golden Ratio has been found lurking in some of the world’s most celebrated creations. Now whether you believe this divine proportion is truly a mark of beauty or simply selection bias is up to you, but without a doubt it is one of the most intriguing numbers in existence. Phi is Golden

Number Sense Activities for the Classroom
The term number sense gets thrown around a lot these days, especially as we learn more about how important it is to our students’ understanding of mathematics. As adults, we use number sense every day: to estimate the cost of a basket of groceries, to measure for new bookshelves, or to calculate how long it will probably take to get to the beach. Numbers are a big part of our daily lives. So it’s no surprise that students develop number sense by making sense of the numbers and quantities in their world. And yet, the mystique around formally teaching number sense has only grown. Building number sense can be seen as serious work, deserving of many hours of instructional time rather than a short, daily practice.
