Description |
| Ants, Hot Dogs, and Fish...Oh, My!: | The learner will relate counting to addition and subtraction by using the strategies "Counting Up" and "Counting Down". This lesson engages students through the use of short videos, manipulatives, literature, and games |
| Duck Addition: | Students will listen to the book, Quack and Count by Keith Baker, and use the information in the book along with manipulatives to create addition equations. Students will then relate the addition equation to a subtraction equation. Specifically, students will be working on creating the addition and related subtraction facts with the number combinations for 7. |
| Show What You Know: Addition and Subtraction Strategies Project: | This project is to be used at the end of the school year once all the addition and subtraction strategies have been taught. This is a review of the strategies and is an excellent way for students to show what they know about their understanding of addition and subtraction strategies. |
| Think Addition and Make a Ten to Subtract: | This lesson will teach students a strategy to subtract one-digit numbers from teen numbers by thinking addition and making-a-ten using double ten frames and two-color counters. This lesson supports previous work with restating subtraction problems as missing addend problems. |
| Flower Power Flower Company MEA & STEAM* Activity: | This STEAM (Science, Technology, Engineering, Art, and Math) lesson has been designed around a Model-Eliciting Activity.
The Flower Power MEA provides students with an real world problem in which they must work as a team to design a plan to select the best flower arrangement for a special event. The resource was primarily designed as an MEA so the time and teacher instructions are based on the MEA format. The additional activities will take several hours of instruction but include watching and discussing a video about the parts of plants, reading a book, and discussing the art in the book as well as additional art by the book author/illustrator. Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom. |
| Show It Another Way: | In this lesson, students will apply properties of addition in order to add three whole numbers. Students will then decompose the sum using tens and ones. |
| Using the "Make-a-Ten" Strategy to Add: | In this lesson, students will use the "make-a-ten" strategy to add two whole numbers within 20. Students will utilize a ten frame and 2-color counters to complete this activity. |
| Planting Vegetables After a Storm: | In this open-ended question, students in teams will make decisions about how to rank vegetables to plant on a farm. The students' decisions will be based on various criteria.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

| Creature Island: | This lesson outlines a game that is a fun and engaging to practice the make a ten strategy, within 20. |
| Sums of Ten Pyramid: | In this lesson, students will play a card game to practice finding pairs of numbers that make 10 when added. |
| One more up on top: | Students will be able to describe how adding by one is like counting up or on. |
| Solving Word Problems Using Story Structure: | In this lesson, students will learn how to use their knowledge of beginning, middle, and end to solve word problems that include result unknown, change unknown, and start unknown. They will learn how to use a modified story map to write an equation to represent the problem. |
| Dangerous Doubles (Doubling Numbers): | This lesson teaches students to use the strategy doubling numbers and doubles plus or minus one in order to use mental math to add one-digit numbers. The students are engaged in learning through the read-aloud of "Double the Ducks" by Stephen Murphy and then get to work with a partner to draw doubles and write equations that relate to their drawings. Students individually work on solving word problems using these strategies and manipulatives as necessary to solve. |
