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.

###
Earth’s Movements

Students will work in small collaborative groups to demonstrate the rotation of the Earth as it revolves around the Sun which creates a day and night cycle.

###
Fractions with Multi-Step Problems

Students will be able to work collaboratively while baking to find the least common multiples of fractions with unlike denominators and create equivalent fractions, then add or subtract.

###
Circuit Designers

**Students will work in small groups of two to three on a structured challenge around circuits which includes requirements such as including using a switch or a conductor. They will then use that knowledge to work on a collaborative challenge to solve a relevant problem related to elephant poaching. Students will create a containment system that will have an alarm system, a lighting system, and a way to pass through. Finally, they will review the other projects and discuss similarities and differences in the design.**

###
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. **

###
45-45-90 Triangles

To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.

###
Particular Polygons

Students will be able to classify 2D figures by analyzing their attributes.

###
From Dogs/Not Dogs to Prisms/Not Prisms

Students will work in pairs, groups, and independently to sort and classify 2D and 3D shapes using formal geometric language. Students will have opportunities to explore the work of other groups to expand their thinking and find new ways that shapes can be sorted and classified. Students will engage in multiple conversations using accurate geometrical language to ask questions, explore a variety of reasonings, and share generalizations about shapes.

###
Courts of Measure

Students will use measurement tools to measure the dimensions of the basketball court and calculate the area of the court.

###
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

**Students will represent fractions in multiple ways, such as pattern blocks, fraction strips, and number lines.**

###
Working with Literal Equations

The lesson will provide a conceptual basis for illustrating the parallelism between solving multi-step equations and translating literal equations into solutions for specified variables.

###
Planting the Seeds of Perimeter

**Students will create planters that meet specific perimeter dimensions. The students will need to determine the number of sides and the perimeter for their planter. **

###
Decoding Word Problems

**This lesson focuses on multi-step word problems involving division along with addition or subtraction. The students chunk word problems into each individual step and learn how to choose a familiar strategy. **

###
What Goes In, Must Come Out

**Students will learn how to use an input-output table using real-world examples.**

###
Trip to the Theme Park

Students will work on a real-world based project in class involving multiplication of decimals requiring budgeting skills.

###
Analyzing Data Using a Dot Plot

Students will construct a dot plot using data collected on the faces of a cube after it is rolled. Students will then use a key to change the data to represent a larger population.

###
Stop, Collaborate, and Rotate

Students will explore the Earth's rotation and its relation to the Sun and the Moon. Then, students will create a visual representation of this relationship and present it to the rest of the class.

###
Models of Multiplication

Students will solve one-step multiplication problems using various multiplication strategies such as objects, pictorial models, arrays, equal groups, repeated addition, and number lines.

###
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.
