This lesson is intended to help students begin to transition away from a one-to-one correspondence. Students at this point should be able to use concrete ojects to identify values.Goal: Students will be able to use a number line to "Count On from Greater"

Once students have the concept of doubles down as a fact strategy they can then use this fact to identify relationships about other number facts. Students recognize the patterns and relationships between the numbers while modelling using concrete manipulatives and diagrams. This is a strategy that uses  Counting On and Doubles as a combined strategy.

Students will use unit cubes (or other counters), spinner, dice,  to build understanding of doubles Working with the doubles strategy is imperative for students to understand how to apply other strategies. Included are several tasks and activities that you can use and/or rotate throughg with students as they progress to proficiency using the doubles strategy. As students work with and learn the doubles strategy (especially at the beginning) they should record their results. This can be done using a sums within 20 addition table which can help students to visualize the pattern.

Provided in the content is only one doubles sheet. To play with more than one student at a time, multiple copies will have to be made with different patterns. Some students will still need to have concrete manipulatives available to them so that the can create the double, or you might ask the students to make a picture to should how they doubled (did they make pairs, did they count out the given value and then make a copy).For each player distribute:1 card.20 counters to mark spaces on the cardCaller should have:1 10-faced die1 spinner split into sixths each sixth should have a letter from the word D-O-U-B-L-E in it.Directions:Have the caller read out a letter-number combination. The caller should roll the die and spinner the spinner to identify the letter-number combination.Place a chip on your scorecard if you have that letter and number. Students will find the letter given by the and will have to double the value from the die since every number on a Doubles card should only have numbers that can be created by doubling. Continue playing until someone gets 5 chips in a row on their scorecard. Othe variations include Blackout (fill the whole card), X Marks the Spot (two diagonal lines that intersect in the middle and include the four corners), Perimeter-or Square (fill all of the spaces on the outside edge), etcShout "DOUBLE” if you get 5 squares in a row (or you have completed the variation).Repeat

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 Illuminations lesson plan students explore the use of variables as they solve for the weights of objects using information presented in pictures. Learners model situations that involve adding and subtracting whole numbers, using objects, pictures, and symbols. A student activity sheet is available and downloadable (pdf).

In this 6-lesson unit, students explore 5 models of subtraction (counting, sets, number line, balanced equations, and inverse of addition) using connecting cubes. The lesson activities focus on the comparative mode of subtraction as children investigate the relationship between addition and subtraction, write story problems in which comparison is required, and practice the subtraction facts. The lessons include printable student activity sheets, a bibliography of children's counting books, questions for student discussion and teacher reflection, assessment options, extensions, and links to online applets (cataloged separately).

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.]

In this unit, students use online pan balances to study equality, order of operations, numerical and variable expressions, and other key algebraic concepts. Lessons focus on balancing shapes to study equality and equivalence; balancing algebraic understanding, to explore simplifying expressions; and balancing algebra, to determine if algebraic expressions are equal.

This is a modification of the Helping With Math lesson, Addition with "Cuisenaire Sandwiches", https://www.helpingwithmath.com/printables/worksheets/addition-subtraction/1oa6-addition-subtraction07.htm. This lesson was used with a tier 3 fourth grade intervention math group to help students understand the inverse relationship between addition and subtraction. I modified it to meet the students' needs by having students find partners of numbers up to 20 and had them write the related subtraction equations instead of just the addition equations. Students also modeled the subtraction with the Cuisenaire Rods.

In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 (1.OA.6). They are presented with opportunities intended to advance them from counting all to counting on, which leads to decomposing and composing addends and total amounts.

Module 2 serves as a bridge from students' prior work with problem solving within 10 to work within 100 as students begin to solve addition and subtraction problems involving teen numbers. Students go beyond the Level 2 strategies of counting on and counting back as they learn Level 3 strategies informally called "make ten" or "take from ten."
