# Early to Late Elementary

A* Creative Math Prompt* is an image (often quite simple) that contains the seeds of a deep math investigation. The prompts are open-ended yet connected to content goals. As you and your students make observations and generate questions to explore, you develop your mathematical creativity as well as problem-solving and reasoning skills.

Ten Plus One:

A Tool for Enhancing the

Depth and Complexity of

Math Tasks

Ten Plus One is a free tool designed to help teachers transform traditional math tasks into new tasks that promote learning with deep understanding. It consists of ten strategies to make tasks deeper and one strategy to enhance complexity.

*Deep Math Projects *are open-ended projects that you can extend by continuing to ask new questions. The problems are self-differentiating and often have multiple solutions and/or solution paths.

Each of the nine Monthly Problem Sets for grade 5 contains a grid of 15 problems designed to challenge talented and adventurous students. The problems are organized by content strand: *Number and Operation; Algebra; Geometry; *and *Data and Probability, Rates and Ratios. *There is also a *General *category just for fun!

mathpickle.com has collection of deep, open-ended, and challenging (some unsolved!) math problems for students of all ages searchable by grade level, including plenty for very young students. Each problem has been found or created by a professional mathematician and fits comfortably into a 45-60 minute time frame.

nrichmaths.org has an extensive collection of rich, engaging math problems searchable by age and concept. There is plenty of support for teachers, and students may submit solutions for possible publication online.

Ken-ken puzzles are like sudoku, but with a challenging mathematical twist. The puzzles develop not only computational facility but problem-solving skills, number sense, and a deeper understanding of number properties. This website will generate ken-ken puzzles for you based on your choice of grade level, mathematical operations, the size of the grid, and level of challenge.

Zukei puzzles involve searching for geometric shapes hiding in grids or dots. The focus is on reasoning about properties of two-dimensional figures. The puzzles come in all levels of difficulty. You and students can easily create your own as well.

James Tanton's *Exploding Dots *has taken the math world by storm over the past couple of years. Using a simple visual model, students explore place value, addition, subtraction, multiplication, division, and beyond in different base systems.

*Beast Academy *is a full math curriculum for gifted and advanced learners in grades 2 – 5. (I would not recommend it for other students.) It is produced by the Art of Problem Solving people who are known for their materials for gifted secondary students. The focus is on problem solving and deep conceptual understanding. An online version of the program is said to be coming soon.

From the same people who produced Project M3 for upper elementary students, Project M2 "contains eight curriculum units designed for grades K-2 to foster inquiry and engage students in critical thinking, problem solving, and communication activities...[with a] focus on “in-depth” mathematics using research-based practices and standards in mathematics education and early childhood education.

This series from Kendall Hunt is well known throughout the US for providing research-based, deep, challenging math curriculum for advanced learners. Each module comes with extensive teacher support, and you may use the projects as curriculum units or as a supplement. The only downsides: materials are rather expensive and require a fair amount of preparation time for teachers.

# Late Elementary to Middle School

*Math Building Blocks* is a free online book in which colored blocks are used to represent prime numbers and prime factorizations. The blocks* *help adventurous learners visualize, analyze, and connect concepts across middle school math standards—everything from factors, multiples, GCFs, and LCMs to fraction computation, properties of exponents and radicals, and algebra.

This excellent youtube challenge presents videos on popular advanced math topics to a general audience. They also challenge viewers to answer questions and solve related problems. Unfortunately, they recently stopped producing new content, but the original content remains available for viewing.

The "Mathologer" is Australian mathematician Burkard Polster, and he makes beautiful and informative videos about popular math topics such as infinity, rubik's cube, irrational numbers, infinity, higher dimensions, fractals, etc. He also likes to give you challenging problems to think about—and he wears very cool math t-shirts!

# Middle School and Beyond

The ACCME book series contains challenging, engaging activities that extend and deepen students' conceptual understanding of advanced middle school concepts.

Deep Algebra Projects are rich, complex mathematical and real-world investigations that stretch advanced learners out of their comfort zones. The projects enhance students' abilities to think independently, flexibly, and with deep understanding.
