This 46-page pdf document demonstrates the connections between the CCSS content standards and the mathematical practice standards. It is a compilation of research, standards from several states, instructional strategies, common misconceptions, and examples for each standard at the grade 1 level. It is intended to help teachers understand what each standard means in terms of what students must know and be able to do. Additional flip books are cataloged separately for grades K and 2-5.
Instructional Strategy, Reference Materials
This web page provides links to resources aligned to the CCSS that guide and support first grade mathematics teaching and learning. Tasks developed by the Mathematics Assessment Resource Service (MARS) and Problems of the Month, (POM home page is cataloged separately) developed by the Noyce Foundation are included. The activities were designed to measure students' ability to solve non-routine problems, explain and justify their solutions, and promote high level thinking skills. Resources are listed for specific grade 1 standards and are also organized by progression for an alternate search route.

This interactive Flash applet helps students learn to compare and order objects according to size and weight attributes. The text and voice prompts ask students to compare three objects to find the longest, tallest, shortest, and so on. It then asks them to place three objects in a specified order, such as narrowest to widest. Correct responses are rewarded with a cheer and a summary of the results. One concern for users might be the British accents of the readers.

These 3 activities, part of the Mathematics Developmental Continuum of the State of Victoria, Australia, are intended to introduce young learners to the measurable attribute of length as distinguished from others. Students compare lengths of two or more objects directly or indirectly. Teaching suggestions and progress indicators are included.

This narrative document describes the progression of Geometric Measurement across the K-5 grade band. It is informed both by research on children's cognitive development and by the logical structure of mathematics. The document discusses the most important goals for elementary geometric measurement. Among those are recognizing measurable attributes, comparing, connecting with number, estimating, and differentiating linear measurement from area and volume.

This blog post presents a Thanksgiving activity that engages learners as they practice measuring with nonstandard units and comparing lengths. Learners use unifix cubes to measure the heights of four turkeys then compare and arrange them in order from shortest to tallest. The last part of the activity has students measuring Tom Turkey to determine which clothing he should be dressed in for dinner. The lesson plan and all student worksheets can be downloaded to a PDF.

This collection of seasonal projects has students apply concepts from geometry, measurement and fractions to the guessing of pumpkin circumference and weight; the creation of jack-o-lanterns, Halloween masks, glyphs, and other autumnal artwork; and more. Measurement Man is constructed to display the unit conversions for measures of capacity. Instructions (pdf) are included. The page continues with other projects that have a Halloween theme, and mentions connections to resources from children's literature.
