In this 8-lesson unit students use buttons to explore logical and numerical relationships that form the conceptual basis for understanding addition and subtraction operations. Topics include counting, ordinal numbers (and relative position), classification (attributes), relationships between numbers, addition of sets, commutativity of addition, sums to 10, fact families (including subtraction), three models of subtraction ("take away", comparative, missing addend), and bar graphs. Includes student activity sheets and a link to an online graphing applet.

In this 6-lesson unit, students use dominoes to explore four models of addition: counting, number line, sets, and balanced equations. They learn about the commutative property, the relation between addition and subtraction, the result of adding 0, and the concept of doubles. Students write story problems which involve the operation of addition and begin to memorize the addition facts. They represent addition in pictures. The various models of addition help students develop a rich conceptual schema for addition. Included are a Bibliography of Counting Books, student materials, questions for student and teacher reflection, assessment and extension ideas. [Suggestion: Use the alternate applet, Pan Balance - Numbers, listed as a Related Resource, rather than Pan Balance - Shapes, in Lesson 4.]

Students can use this interactive Flash applet to practice subitizing and counting groups of objects, to understand the importance of 5 in our base-10 number system, and to learn basic addition facts. In the four included games students construct groups of 5 objects, add groups of objects within 10, and identify and record numbers within 10. Auditory prompts support students with limited reading ability.

Module 4 marks the next exciting step in math for kindergartners, addition and subtraction! They begin to harness their practiced counting abilities, knowledge of the value of numbers, and work with embedded numbers to reason about and solve addition and subtraction expressions and equations. In Topics A and B, decomposition and composition are taught simultaneously using the number bond model so that students begin to understand the relationship between parts and wholes before moving into formal work with addition and subtraction in the rest of the module.

This interactive Flash applet helps students develop number sense and fluency with addition and subtraction facts within 10. Okta hides some bubbles under a shell, and then either adds more bubbles or takes some away. Students determine how many bubbles are left under the shell. Users can choose a specific one-digit starting number or let the applet choose randomly. Users can select addition, subtraction or both.

This is a 3-Act-Task in which students will solve the problem 9 - 5 = ? or 5 + ? = 9. No guidance is given as to how to solve the task, so student can invent a strategy that works for them. Solutions may include drawing a picture, writing a number sentence, etc. Discussion should be centered around how to represent the context of this scenario with pictures, words, and numbers.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials * Double sided counters * Markers that are the same colors as the counters * Teacher-made “My Book of 5” (see below for detailed directions) ...

In this lesson, students practice addition (subtraction optional) and deductive reasoning skills to solve KenKen puzzles, which is a break off of the Sudoku puzzle. All of the directions of what a KenKen puzzle is and how to use them are included in the resource in detail. The students investigate as a group what they think is happening in a completed puzzle. In this way they are using the Math Practice Standards MP1 and MP7. Once they understand the rules, they will work on solving problems using addition and possibly subtraction.

Module 1 of the Kindergarten curriculum in A Story of Units. In Topics A and B, classification activities allow students to analyze and observe their world and articulate their observations. Reasoning and dialogue begin immediately. In Topics C, D, E, and F, students order, count, and write up to ten objects to answer how many? questions from linear, to array, to circular, and finally to scattered configurations wherein they must devise a path through the objects as they count. In Topics G and H, students use their understanding of relationships between numbers and know that each successive number name refers to a quantity that is one greater and that the number before is one less.

This google slide show will be used by grade 1 teachers with their students as a numeracy routine. Students should be given time to notice and wonder about each slide. Focus is on composing and decomposing numbers as well as discussion of addition and subtraction strategies. Steve Wyborney is the original creator.

In this unit of 8 lessons, students make groups of zero to 10 objects, learn number names for the groups, compose and decompose numbers, and practice writing numerals to record the size of a group. Each lesson includes visual, auditory, and kinesthetic activities and supporting materials, questions to facilitate student thinking and teacher reflection, assessment suggestions, and a link to online applets that support the unit.
