1st Grade Math Unit 3

Big Idea:

Identifying and creating 2-Dimensional shapes

Student Expectations:

Priority TEKS

1.6C [Supporting] Create 2D figures, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons

1.6F [Supporting] Compose 2D shapes by joining two, three, or four figures to produce a target shape in more than one way if possible

Focus TEKS

1.6A [Readiness] Classify & sort regular and irregular 2D shapes based on attributes using informal geometric language

1.6D [Readiness] Identify 2D shapes, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons and describe their attributes using formal geometric language

Ongoing TEKS

1.2(A-C)Number and Operations - The student applies mathematical process standards to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to: (A) recognize instantly the quantity of structured arrangements; (B) use concrete and pictorial models to compose and decompose numbers up to 120 in more than one way as so many hundreds, so many tens, and so many ones; (C) use objects, pictures, and expanded and standard forms to represent numbers up to 120.

1.3D [Supporting] Apply basic fact strategies to add & subtract within 20, including making 10 and decomposing a number leading to 10;

1.3E [Supporting] Explain strategies used to solve addition & subtraction problems up to 20 using spoken words, objects, pictorial models, and number sentences;

Student Learning Targets:

• I will be able to sort shapes by attributes in more than one way.
• I will be able to create 2D shapes
• I will be able to make new shapes from other shapes
• I will write about my shape picture

Essential Questions:

• Why are shapes important in our world?
