This lesson fosters a student's conceptual fraction sense with proper fractions, improper fractions, and mixed numbers by placing thirty fraction cards in order between given whole numbers on a number line clothesline. Users will visually identify that all proper fractions are grouped between zero and one, and that improper fractions or mixed numbers are all grouped above one. Users also play an estimation game with groups using the same principle. Instructional plan, questions for the students, assessment options, extensions, and teacher reflections are given.

This lesson unit is intended to help teachers assess how well students are able to: articulate verbally the relationships between variables arising in everyday contexts; translate between everyday situations and sketch graphs of relationships between variables; interpret algebraic functions in terms of the contexts in which they arise; and reflect on the domains of everyday functions and in particular whether they should be discrete or continuous.

In this five lesson unit with overview from Illuminations, student activities explore relationships among fractions through work with the length model. Students construct fraction strips and use fraction bars throughout the unit to make sense of basic fraction concepts, to compare fractions and order fractions and to work with equivalency in fractions. Specific learning objectives, a material list, an instructional plan, questions for the students, assessment options, extensions, and teacher reflections are given for each lesson.

This unit from Illuminations consists of five lessons designed to help students understand fractions when they are represented as a part of a region. Learners investigate relationships between parts and wholes, the relative value of the fraction based on the pattern block shape and equivalency while working with physical and/or virtual pattern blocks. Instructional plan, questions for the students, assessment options, extensions, and teacher reflections are given for each lesson.

This lesson unit is intended to help you assess how well students working with square numbers are able to: choose an appropriate, systematic way to collect and organize data, examining the data for patterns; describe and explain findings clearly and effectively; generalize using numerical, geometrical, graphical and/or algebraic structure; and explain why certain results are possible/impossible, moving towards a proof.

This tool allows you to learn about various geometric solids and their properties. You can manipulate each solid, seeing it from every angle. You can also color each shape to explore the number of faces, edges, and vertices. With that information, you are challenged to investigate the following question: For any polyhedron, what is the relationship between the number of faces, vertices, and edges?

This lesson unit is intended to help teachers assess how well students are able to use geometric properties to solve problems. In particular, the lesson will help you identify and help students who have the following difficulties: solving problems by determining the lengths of the sides in right triangles; and finding the measurements of shapes by decomposing complex shapes into simpler ones. The lesson unit will also help students to recognize that there may be different approaches to geometrical problems, and to understand the relative strengths and weaknesses of those approaches.

This interactive lesson encourages young students to solve problems by estimating angles and distances. They use an applet to give LOGO-like commands, e.g. forward (length), turn (right or left) to make a path that moves a turtle to a pond. Students can create a Path 1 and Path 2 and try to minimize the total path length. There is a newer applet (Turtle Pond, cataloged separately) that allows for adding or editing the commands and a choice of right angles only, or angles in multiples of 15 degrees. The lesson provides suggestions for implementation and discussion questions.

This google slide show will be used by first grade teachers with their students as a numeracy routine. Students should be given time to notice and wonder about each slide. Multiple opportunities to count objects exist within each slide's photo. The slides build upon the counting collections strategy, which involves multiple ways to count collections of physical objects.

This google slide show will be used by second grade teachers with their students as a numeracy routine. Directions for the teacher are found here. For quarter two, students will estimate using pictures. Students should be given time to notice and wonder about each. Using a number line range is a good technique.

This google slide show will be used by second grade teachers with their students as a numeracy routine. Directions for the teacher are found here. For quarter three, students will estimate using pictures with clues. Students should be given time to notice and wonder about each. Then, students can adjust their estimates as clues are revealed. Using a number line range is a good technique. This resource has been adapted from the work of Steve Wyborney.

This google slide show organizes numberless word problems in a sequence by weeks. This series is recommended for second graders in the third quarter. Teachers can use these with students to promote number sense, composing and decomposing, making sense of word problems, and precise mathematical vocabulary.

This google slide show organizes "Who Am I?" number puzzles in a sequence by weeks. This particular selection has been chose for Grade 2, second quarter use. Puzzles are online and linked to this slide show. Teachers can use these with students to promote number sense and precise mathematical vocabulary.
