In this problem learners practice addition, subtraction and multiplication while developing logical reasoning. Solvers apply the given clues along with their understanding of the domino numbering system to determine which dominoes are missing from a set. The Teachers' Notes page includes suggestions for implementation, discussion questions, ideas for extension and support, printable sheets of dominoes (pdf), and a link to an interactive Dominoes Environment (cataloged separately).

This web site contains information and interactive applets related to our Hindu-Arabic number system. Users learn the history and structure of the system as well as how to count and write numbers. Users can learn and practice various algorithms for whole number computation and explore fractions, decimals and percents in our number system. The site explains various sets of numbers and how they relate to operations.

This lesson plan helps students understand multi-digit division by constructing area models. The included interactive provides two example problems and helps connect the model to the traditional long division algorithm. Students solve their own problems using graph paper and/or base-10 blocks and progress toward mental strategies.

In this practice guide the Institute of Education Sciences (IES) provides reseach based guidelines for implementing a school or system wide intervention program. The guide identifies eight recommendations to help educators use response to intervention practices, provides a brief description of each, establishes the relative strength of the research base, and discusses difficulties that may occur in implementing these interventions.

This problem, from the collection of Aunty Mathilda challenges, promotes algebraic thinking and problem solving strategies. Aunty Math must determine the individual weight of her two nephews and niece given clues about their combined weight. Included are links to an easier challenge and to a harder one, depending on the level of the solver, and a link to a page for parents and teachers with additional background support, alignment to the CCSS, explanations and extensions.

This interactive Java learning tool, which was constructed using the cross-platform open educational resource GeoGebra, allows a teacher to demonstrate and explore integer operations with students using two different balloons and sandbags models. Drag balloons, sandbags, and/or zero pairs onto the board and students see how the total result shown on the board changes the models. Nine pre-set integer addition and subtraction problems are given, as well as the ability to create your own problems (option 10). An alert is given when the first term of each expression is formed. (The models can also be used during discussions of multiplication and division, although no problems are included.)

This 8-page monograph explains bansho, a research-informed instructional strategy for mathematical communication and collective problem-solving. Following a brief overview, the article outlines how bansho can be used to plan and implement an effective three-part problem-solving lesson. Bansho can be incorporated into collaborative planning sessions, in which teachers work with partners or in groups within communities of practice to learn about mathematics for teaching. The author provides a sample grade 2 lesson on the development of multiplication concepts and a list of references.
