🔵 Connect Addition Strategies to Algorithms Practice Day 32

Connect Addition Strategies to Algorithms

Introduction

Mathematicians! Now that you have noted the relationships between the strategies you have been using to add whole numbers and the standard algorithm, we will take several opportunities to practice. In this lesson, you will practice using the standard algorithm in order to decide if the given statements are true. Remember, as you add the values in each digit place, remember the value of that place and the patterns within our place value system. For every 10 tens, you bundle 1 ? 1 hundred! That pattern will truly help you to master the standard algorithm of addition.

329+54 = (9+4=13 = 1 ten 3 ones; 1 ten + 2 tens + 5 tens = 8 tens; + 3 hundreds = 383)
