Relate Place Value (base 10 block) addition to standard algorithm addition Part 1 - Lesson for Grade 1, Chapter - Addition and Subtraction 20-100
In this lesson, "Relate Place Value (base 10 block) addition to standard algorithm addition Part 1," Grade 1 students will embark on an enriching journey to deepen their understanding of addition within the range of 20-100. Through engaging activities such as the "Different Ways to Add Worksheet," "Adding with Base 10 Blocks Worksheet: Check Yourself," and "Let's Regroup to Add" alongside its complementary worksheet, students will learn to visually and conceptually grasp the concept of place value in addition. They will explore how breaking down numbers into tens and ones using base 10 blocks can simplify the process of addition. This foundational skill is crucial as it aids in developing mental math strategies and understanding the standard algorithm for addition—a method they will use throughout their academic journey and daily life.
By relating place value knowledge to addition, students will enhance their number sense, a key component in the broader mathematical understanding. This lesson aims not only to teach them how to add larger numbers confidently but also to foster a deeper comprehension of how numbers work together, setting a solid foundation for more complex mathematical concepts in the future.

Activity 1 / Different Ways to Add Worksheet
Having access to different strategies is a crucial facet to solving math problems. This worksheet will give your student practice matching equations using the appropriate base ten pictures and math facts. They'll work on fine motor skills with the traceable lines, and you'll watch their number sense grow as they make connections with different ways to add and add to their math skill sets.

Activity 2 / Adding with Base 1 Blocks Worksheet: Check Yourself
We want to build automaticity with math facts in our students, but we also want to stress the importance of being able to check their work. Let your little learner use this colorful worksheet to practice solving addition problems without renaming, and then being able to check their answers using the Base 10 picture representation for further, deeper understanding. It's also good practice for selecting the right answer from multiple choices.

Activity 3 / Let's Regroup to Add
-
Activity 4 / Let's Regroup to Add Worksheet
Being able to regroup and rename numbers is important when doing addition of numbers over ten. This practice worksheet will let students have the opportunity to regroup numbers using base ten blocks representations and rename them so they can use '10s' to add two numbers. They'll develop a deeper sense of mathematical reasoning and learn there really is more than just 'carrying the 1' when it comes to regrouping and renaming!
