This lesson unit is intended to help you assess how well students are able to: Calculate the mean, median, mode, and range from a frequency chart; and to use a frequency chart to describe a possible data set, given information on the mean, median, mode, and range.

Multiplication Strategies and Introducing Area, and adapted OER by Madelyn Mashburn, Creative Commons Attribution , Original work by Nicole Norris: https://docs.google.com/presentation/d/1bbsno3bJ4_vL4oHafiabkMC47eAC1V-G-YEX8KWR6zs/edit#slide=id.p. This OER has been adapted by redesigning the PowerPoint to include more graphics and examples, along with teaching resources for each multiplication tool. The resources for introducing area have been included to reinforce ideas from the original work by Nicole Norris, but to provide more options for both small group and whole group instruction.

Students use a hundred board to eliminate numbers after reading each clue. Students must apply their knowledge of even-odd, multiples and place value to successfully eliminate numbers until the solution is revealed.

These logic number puzzles help students develop strong number sense as they work, clue by clue, to identify the digits of the missing number. The mixed-skills clues incorporate even-odd, less than-greater than, operations (sum, difference), multiples of 5 and 10, geometric terms (octagaon, pentagon, hexagon, quadrilateral, trapezoid, parallelogram), money (quarters, nickels) and measurement (cup, pint, quart, gallon). Students must squeeze every bit of knowledge from each clue to eliminate possible digits until they finally identify the missing digits.

The Standards’ focus on arithmetic can allow greater variety in the tasks students see, giving students time to synthesize their developing knowledge and practice their calculation skills to fluency. One important place to have variety is in the addition and subtraction situations that students see in word problems. The case of addition and subtraction word problems reflects the general truth that there’s more to arithmetic than initially meets the eye.

This course features a video review and an assessment practice of subtracting by crossing out with pictures for word problems. It is aimed at first grade math students.

Once students have developed conceptual understanding of the basic operations they need to develop fluency with the facts. One quick way to include daily practice and motivate students to master these basic facts is through the use of the Who Has? card decks. These decks can be created for virtually any topic and frequent use as both a whole class practice or as a center activity for partners or small groups will provide facts practice in a highly-motivating format.

There are many possibilities for winter math data collection activities. Look for opportunities to have students create tally charts, clothespin graphs, Venn diagrams, bar and line graphs to organize data and analyze the results of the data collection. Build on students' natural fascination with penguins by including these math pattern activities. The Koch Snowflake is an example of an iterative drawing as each successive stage begins with the previous stage. The Koch snowflake begins with an equilateral triangle.

This workbook focuses on developing a foundational understanding of arithmetic for future elementary teachers. Place value, fluency (thinking strategies), operation meaning, rational numbers, and explaining the standard algorithm are at the heart of these materials. Each unit aims to address one of the operations as well as provide a stronger understanding of rational numbers (decimals, fractions, percents).
