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.

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 5-lesson unit is intended to help children who already understand the meanings of addition to develop fluency with addition facts. The activities and games take advantage of commutativity, the additive identity, doubles, and number patterns to develop operation sense and foster retention. Lessons include student materials, questions for students and teachers, assessment ideas, and links to interactive applets.
In this 6-lesson unit students use pasta shapes to explore the take away model of subtraction in several different contexts (counting, sets, number line, balanced equations, and inverse of addition). They decompose numbers, explore the zero property, act out subtraction situations with objects and pictures, record differences with vertical and in horizontal notation, create fact families, find differences with a calculator, and compose and solve problems involving subtraction. The lessons include student activity sheets (pdf), questions for student discussion and teacher reflection, assessment options, and links to online applets.
In this lesson students find and record addends that sum to ten in three different activities, using ten frames, linking cubes, two-sided counters, and a concentration game. The lesson includes suggestions for assessment and extension, reflection questions for students and teachers, links to related resources, and printable materials (pdf).
Making a 10 provides a technique to help students master single digit addition. The task is designed to help students visualize where the 10's are on a single digit addition table and explain why this is so. This knowledge can then be used to help them learn the addition table.

En este primer módulo de Grado 1, los estudiantes avanzan significativamente hacia la fluidez con la adición y la resta de los números a 10, ya que se les presenta oportunidades destinadas a avanzar de contar todos a contar con el que lleva a muchos estudiantes a descomponerse y componer los sujetos y el total cantidades.

El módulo 2 sirve como un puente del trabajo previo de los estudiantes con la resolución de problemas dentro de 10 para trabajar dentro de los 100 a medida que los estudiantes comienzan a resolver problemas de adición y resta con el número de adolescentes. Los estudiantes van más allá de las estrategias de Nivel 2 para contar y contarse a medida que aprenden estrategias de nivel 3 llamadas informalmente "hacer diez" o "tomar de diez".

English Description:
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."

In this six lesson unit, students recognize and explore the relationships among pennies, nickels, dimes, and quarters. They estimate and count sets of mixed coins, create equivalent sets, write story problems that involve money, and use coins to make patterns. Within the unit there is a link to US Mint. http://www.usmint.gov/kids/teachers/
In this math lesson, learners practice addition facts (with sums of 5, 6, 7, and 8) in a concentration-game format using dominoes. Then, learners generate sums of given numbers using a calculator, record the sums on a hundreds chart and look for patterns. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.
Thinking about numbers using frames of 10 can be a helpful way to learn basic number facts. The four games that can be played with this applet help to develop counting and addition skills. (This applet works well when used in conjunction with the Five Frame applet.)
In this math lesson, learners listen to a poem about money from Shel Silverstein's "Where the Sidewalk Ends" and examine a quarter. Learners find sets of coins equivalent to a quarter using pennies, nickels and dimes. Learners also estimate and count coin collections and count by fives and tens using actual and online calculators and pose and answer coin puzzles.
This unit is a Math Routine to use with a Literacy Unit about The Three Little Pigs. I included student work and projects. I created this slideshow to share with the students as we went through each routine. The routines revolve around the construction of houses. This was used in a first-grade classroom. The students persevered to solve the Lego brick problem although it may have been more difficult than first-grade standards.
