The purpose of this task is to study some patterns in a small addition table. Each pattern identified persists for a larger table and if more time is available for this activity students should be encouraged to explore these patterns in larger tables.

Students use this puzzle to practice 2-digit addition. There are two puzzles: one without regrouping and one with regrouping. These puzzles make a great math station/center as students are able to independently check their work. Students can also use this resource as a math choice for when they finished their work.

This is a modification of the Illustrative Math lesson, "Ford and Logan add 45 + 36," https://www.illustrativemathematics.org/content-standards/tasks/2068. This lesson was used with a tier 3 fourth grade intervention math group to help students develop their understanding of place value and use of tens language when adding two digit numbers. I modified it to meet the students' needs by adding ways two other students (Sarah and Tammy) solved the problem: Sarah said, "I know 4 tens plus 3 tens is 7 tens; 5 ones plus 6 ones is eleven ones which is 1 ten and 1 one so 4 tens plus 3 tens plus 1 tens is 8 tens and the one left so the answer is 81." Tammy said, " 45 plus 30 is 75, plus 6 more is 81." Students analyzed and discussed all four methods and compared them to their own methods. I then had students practice using the tens and ones language (like Sarah) for some more addition problems without using place value blocks or models.

In this data analysis activity students investigate data in connection with recyclable materials and develop plans to help the environment. Students collect data about aluminum can usage and graph that data in a line plot. The lesson includes student worksheet and extension suggestions.

In this lesson students use a rule of thumb about the weight of babies to practice doubling and halving numbers. They complete an organized table and compare data using vertical and horizontal double bar graphs. The lesson includes a student activity sheet and extension ideas.

In this lesson plan students conduct a survey of ten students, collect data in a tally chart, and then display and analyze the results in a bar graph. In the analysis students must compare numbers, add, and subtract using the data in the bar graph to generate questions as well as answer them. The lesson plan includes a graph template, a link to an interactive graphing tool, extension questions, and a fact family sheet to show the related facts from their graph analysis.

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 lesson, students explore arithmetic patterns to help solve a real-world problem involving addition operations. This lesson supports the 3rd grade standard of identifying arithmetic patterns and explaining them using properties of operations.

However I did an extension off this lesson using this resource to allow teachers to work on the skills of addition, the precise language of tens and some extra ones, and seeing groups of ten.

This activity is a great way to include Language Arts along with Mathematics. Using The Very Hungry Catepillar, we used based-ten blocks to place onto a ten frames. Each time the catepillar eats something, we add to the ten frame. At the end of the story, we look at how much the catepillar has eaten. However, I took this activity a step further to continue strengthening the use of addition. Students and I then had a variety of situations at the end of the story where the catepillar ate 4 more leaves. The students then add four more, either in a group of 4 or counting out 4 individual items. We then look again at using our language of, "I have a 3 groups of ten and 4 extra ones."

Challenges with this lesson is making sure the students have added a cube onto their ten frame for each item they ate. As well, students would have to also understand how to use a ten frame before the start of the lesson. As well, if you are working to be precise with the language of tens and extra ones, you want to nudge your students to use this language. You will want to model this multiple times.

In this lesson from Illuminations, students explore and discover linear relationships. Linear patterns are identified, extended and described verbally, numerically and algebraically through three investigations. Using manipulatives and the linked applet, "Chairs", learners determine the number of chairs needed when the number of tables is known, and vice versa. Instructional plan, questions for the students, assessment options, extensions and teacher reflections are provided.

This lesson develops number skills, understanding of coin values, and the concept of equivalence. Students use coin blocks, concrete representations of the value of coins (pennies, nickels, dimes, and quarters), to compose and decompose values up to a dollar. The resource includes a 3-minute video for teachers on how to build the coin blocks prior to the lesson. An interactive game, Coin Box, provides additional practice for students and is cataloged separately.
