Who Ate More - Fractions on a Number Line

In this activity, students will consider a real-world scenario requiring them to compare two fractional amounts using a number line. Through the use of the number line and peer collaboration, students will recognize equivalency in the two fractional quantities and effectively communicate their understanding of this concept.

###
Word problems, models and more!

**The students will engage in group activities to solve word problems with and without models as well as writing equations. **

###
Composing and Decomposing a Number

In this lesson, students will learn how to compose a number with base 10 blocks, decompose a ten, and then compose the same number a different way.

###
Crime Scene Two Steppers: Two-step word problems using multiplication and division

Students will collaboratively solve two-step real-world word multiplication and division problems by using a checklist. Students will also solve a two-step word problem by completing a hands-on group activity.

###
Colorful Fractions

###
Utilize Strip Diagrams to Solve Multi-step Multiplication and Division Word Problems

Students will utilize manipulatives to create concrete and pictorial strip diagram representations in order to solve multi-step multiplication and division word problems.

###
It’s All About the Bend, No Breaking

Students will experiment with choosing tools to measure around a previously created pet habitat in preparation for choosing appropriately sized food bowls. Students will use a graphic organizer to record tools chosen and to explain why those tools were or were not a good choice for continuous measurement.

###
Subtraction Seekers

Students will be introduced to subtraction in an inquiry-based lesson that uses concrete examples and allows students to explore through different settings and scenarios.

###
Distributive Property

Students break an array apart to represent the sum of two multiplication facts, showing the distributive property.

**Texas Essential Knowledge and Skills (TEKS) Related to the Unit**

As we looked at the vertical alignment document available to teachers through the Texas Education Agency and regional TEKS resource pages, it became evident why students struggle with this standard. The skills and knowledge within this standard are not addressed in the second-grade TEKS. Students are also required to use multiple skills to correctly calculate the answer using the distributive property. The chosen standard is identified as a third-grade readiness standard, which means that the intent is to help students develop a deep understanding of how to effectively use these skills in mathematics. This deep understanding is desired to help students at the fourth-grade level since the standard is identified as a supporting standard.
