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.

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. 
 

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

The teacher will introduce Fact Families through literature. Students will create and represent various Fact Families within 10.

Students will work collaboratively to solve six real-world multiplication problems and earn puzzle pieces they can put together to reveal a phone number they can call to escape the classroom.

Students will work collaboratively with a partner to discover what is a line of symmetry.

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.

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.

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.

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

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

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.

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.

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.

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.
