學習目標
Students will be able to add and subtract 2-digit numbers using regrouping.
教學大綱
6 課程
超過 6 週課 1:
Place Value
Students will know and be able to represent the value of 2-digit numbers. We will discuss place value in the tens and ones as well as represent 2-digit numbers using standard form, models, and expanded form. 課 2:
Addition with Regrouping Using Models & Expanded Form
Students will be able to add 2-digit numbers with regrouping using models and expanded form. We will learn how to make new tens (regroup) using models to represent what is happening. We will also learn how breaking numbers apart into expanded form can help us to add 2-digit numbers together when regrouping is involved. 課 3:
Addition with Regrouping Using Standard Form
Students will be able to add 2-digit numbers with regrouping using the standard form for addition. This is where we write the equation vertically, add the ones, and "carry" the new ten to the top, finally adding the tens together. 課 4:
Subtraction with Regrouping Using Models & Expanded Form
Students will be able to subtract 2-digit numbers with regrouping using models and expanded form. We will learn how to break apart a ten (regroup) using models to represent what is happening. We will also learn how breaking numbers apart into expanded form can help us to subtract 2-digit numbers together when regrouping is involved. These strategies are both really helpful in representing to students how a ten is being moved over to the ones. 其他詳情
