# Relate Place Value (base 10 block) addition to standard algorithm addition Part 2 - Lesson for Grade 1, Chapter - Addition and Subtraction 20-100

In this engaging lesson, titled "Relate Place Value (base 10 block) addition to standard algorithm addition Part 2," first-grade students will dive deeper into the world of addition and subtraction, focusing on numbers 20-100 within the unit "Foundations in Operations Within 100". Students will explore the crucial concept of place value and its relationship to the standard algorithm of addition, an essential skill for their mathematical development.

Throughout this lesson, learners will engage in hands-on activities such as the "Regrouping With Base Ten Blocks Worksheet", "Let's Regroup Worksheet", and "What Equation Is That? Worksheet". These activities are designed to solidify their understanding of regrouping—a key aspect of adding larger numbers. Moreover, the "Relate Place Value Addition to Standard Algorithm" activity will enable students to see the direct connection between concrete, visual representations of numbers and the more abstract standard algorithm method of addition.

Understanding these concepts is vital for students as it lays the groundwork for all future mathematical learning. Mastering the relation between place value and standard algorithm addition aids in developing computational fluency, problem-solving skills, and numerical literacy.

• ### Activity 1 / Regrouping With Base Ten Blocks Worksheet

The numbers in this simple worksheet need to be regrouped and solved. Your kids will need to be able to count properly, as well as add up numbers in base ten in order to successfully complete this exercise. There are four equations in the picture. Each one has a set of base ten blocks, and simple addition problems underneath the blocks. Ask your child to regroup to solve the addition problems, and then help them check the correct sum.

• ### Activity 2 / Let's Regroup Worksheet

Counting is fun! Help teach your child this by using fun and colorful worksheets such as this one. If your child is still struggling with adding simple sums, or counting high numbers, then you definitely need this mathematics printout to help them get a hang of the simple problems. There are three problems in the picture. Each of them has an equation at the top. Help your child figure out the correct answer by adding the numbers, and then trace a line to the correct sum for each equation.

• ### Activity 3 / What Equation Is That? Worksheet

Learning to count in base ten blocks will help your students with some of their mathematics struggles. The only way they can get better at it is with constant practice, so assign them as much homework and worksheets as you can. The exercise is simple; ask your students to trace a line to the correct equation illustrated by each group of base ten blocks. You will need to help them count the base ten blocks, and then hold their hands as they trace the lines in this tracing sheet.
