In this game students explore the concept of probability in conjunction with addition of money. The object of the game is to have the most money at the end or reach $5 first. Throughout the game students collect coins for the number(s) rolled on each turn, but once the number 1 is rolled they lose all that they haven't banked. | Game Grade Level: 2, 3, 4 | |

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. | Instructional Strategy, Reference Materials, Article Grade Level: K, 1, 2, 3, 4, 5 Resource is part of a PD collection | |

This collection from NRICH provides activities to help learners think and work like a mathematician. Tasks have students exploring, questioning, working systematically, visualizing, conjecturing, explaining, generalizing and justifying. Activities are organized under specific strategies and processes. | Activity, Interactive Media, Problem Set Grade Level: 1, 2, 3 | |

In this formative assessment lesson students identify patterns (both linear and exponential) in a realistic context. They may solve this problem through a variety of strategies, providing opportunities for groups of students to share and critique various problem solving approaches. | Activity, Lesson Plans Grade Level: 4, 5, 6+ | |

This web page contains links to a video and several downloadable pdf files documenting the efforts of a third grade class to prove a set of conjectures about even and odd numbers. Included are a 4-minute Blue Stream video segment in which students discuss a classmate's conjecture that the sum of two odd numbers always equals an even number, a document providing background information on the investigation that led to the discussion, a transcript of the video, and the teacher's journal entry reflecting on the discussion and its implications. | Activity, Demonstration, Video Grade Level: 2, 3, 4, 5 Resource is part of a PD collection | |

In this 8-minute video kindergarten teacher Karen Lassiter models a lesson designed to help children understand place value with the numbers 11-19. She explains her use of a 10-frame in developing understanding of counting on, addition, and notation. The resource includes reflection questions for viewers, a transcript of the video (doc), and a lesson plan (pdf). | Instructional Strategy, Video Grade Level: K, 1 | |

In this statistics lesson on bias sampling students conduct a poll of specific populations within their school to determine recommendations for homework policies. Each of three groups is assigned a population to survey and then reports their conclusions to the class. Students will then determine how to improve their survey in order to get unbiased results. A student worksheet for questions and a student template for a letter to the principal are included. | Activity, Lesson Plans Grade Level: 3, 4, 5 | |

This problems is an opportunity to explore triangular numbers in the familiar context of decorating a birthday cake with a number of candles corresponding to a child's age. The problem lends itself to systematic strategies and multiple representations. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support. | Activity Grade Level: 1, 2, 3 | |

In this problem students explore the concept of proportion by comparing the relative strengths of different mixes of juice flavor and water in a visual context. Given four mixtures represented by purple and white rectangles, students order the drinks from strongest to weakest flavor and explain their reasoning. The Teachers' Notes page offers suggestions for implementation, discussion questions, and ideas for extension and support. | Activity Grade Level: 3, 4, 5, 6+ |
