Students will subtract using a number line and apply base ten strategies to demonstrate their understanding of taught concepts.

## Number Line Labeling Worksheet Activity #15-AccuTeach

## Objective:

The aim of this exercise is to allow students to demonstrate proficiency in modeling decimals to the tenths place.

## Standard: 5.NBT.A.3

Read, write, and compare decimals to thousandths.

## 5.NBT.A.2 Power of Ten Speed Drill Activity #9-AccuTeach

## Objective:

This activity can be used by the teacher to as an exit-ticket or quick assessment to see whether or not students understand the concept of the power of ten when multiplying.

## Standard:

5.NBT.A.2

Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

## Blank Multiple Place Value Charts 5NBTA2 # 5-AccuTeach

Objective: These place value charts can serve as initial guides. These guides will allow students to demonstrate the effect of either multiplying or dividing by powers of ten. Eventually, as the students become more comfortable, they should be able to sketch these charts on their own to model the multiplication and the division of numbers by the powers of ten, writing numbers in expanded form, etc.

Standards: 5.NBT.A.2

Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

## Math Activity 5NBTA2 One Pager #4-AccuTeach

Objective: The objective of this exercise is to model how to divide decimals by applying the powers of ten and base-ten principles. The students will understand that when dividing a number by powers of ten the number decreases in value.

Standard: 5.NBT.A.2

Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

## Math Activity 5NBTA2 One Pager #3-AccuTeach

Objective: The objective of this activity is to demonstrate to students how the base-ten system works as far as it relates to the power of ten and decimals.

Standard: 5.NBT.A.2

Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.
