This product is part of a series that double as digital lessons for the concept development portion of the Engage New York Eureka lessons and also has interactive Google slides for student practice. Join the Math Detectives as they solve number mysteries today at a baseball game! The focus of this lesson is finding equal number sentences and identifying if they are true or false. If they are false, students will learn to use strategies modeled by the Math Detectives to make the statement true.

The students will learn to use their critical thinking skills based on their fluency of known facts to identify true equations as well as amend false equations to balance correctly. When identifying two equal parts by adding each side, students will visually see and understand the true meaning of equal amounts when represented as two addition sentences. Using eye-catching visual scenes, the Math Detectives go step by step in the lesson portion of this product to solve their mystery of solving each quantity to determine if it shows balanced amounts on either side of the equation.
The lesson begins with identifying the number of players on each baseball team. Students will recognize a fair team as having equal numbers. Each scene in the digital lesson portion of this product demonstrates how to use 5 dot cards and other strategies for counting on. Following the lesson are independent slides. This product promotes independence by following the model "I do, we do, you do" for gradual release of responsibility for students to become independent in mastering this objective. PLEASE NOTE: The lesson portion is to be displayed in present mode.

This product has interactive Google slides for independent or small group practice after the whole group lesson to be shared on your interactive whiteboard or other screen and the practice portion can be assigned in Google Classroom or Seesaw (this portion is interactive only when in edit mode but can be presented in present mode and annotated using Smartboard tools or Zoom annotation tools if using them as guided practice done together). This lesson supports CCSS Operations and Algebraic Thinking, particularly CCSS.1.OA.7. It is designed for early first grade (more specifically it is aligned with Module 1 Lesson 18 of Eureka) but can also be used for second half of kindergarten to address operations and algebraic thinking standards.

The slides in this product line are designed to appear as though you are looking through binoculars, using a camera to take photos, using a magnifying glass, and taking notes on a notepad - just like a real detective hunting for number clues! This lesson will help them conceptualize fluency as well as improve their accuracy in addition and subtraction by determining if equations are true or false. The scenes in this product presents a storyline similar to word problems and promotes problem-solving skills and is designed to promote student discourse and discussion to learn to explain their mathematical thinking.

Use this lesson as whole group shared on your Interactive whiteboard in the classroom, share on your screen on Google Meet or Zoom for distant learning, or displayed for a small group lesson. Remember, use the lesson portion in present mode! Each slide is annotated with dialogue in speech bubbles to guide your lesson, but feel free to make it your own! These lessons cover the Concept Development portion of Eureka lessons, serve as an engaging visual lesson for your students, all while making it no-prep for you as the teacher! Each slide is designed to serve as a foundation for which math discourse in the classroom can build and grow!

After the lesson are 20 independent slides for students. You can assign these slides in Google Classroom or on Seesaw (or any other program that supports Google slide products). Simply hold "ctrl" to select the slides you want to assign, go to file and make a copy. From there you can assign as you normally would on your preferred digital platform. These slides are interactive when in edit mode only! These slides are great as a supplement for the Problem Set in Eureka, independent practice, homework, or for virtual math centers.
