 Patterns, Relationships & Algebraic Thinking (3.6)   The student uses patterns to solve problems. (A)  identify and extend whole-number and geometric patterns to make predictions and solve problems Brenda's Bedroom Border - [this link opens on a new page] Students complete a pattern. (Author - Paulette Boggs) Christmas Lights - [this link opens on a new page] Students identify and complete patterns. (Author - Kaye Maddox) The 'Less than' Lake Maze - Help Monster cross the lake by jumping from one stepping stone to the next. The next number on a stone must be smaller than the one before. The 'More than' Marsh Maze - Help Monster cross the marsh by jumping from one island to the next. The next number on an island must be more than the one before. Missing Numbers - [this link opens on a new page] Students find the missing numbers in a sequence. (Author - Carol Senn) Number Cracker - guess what number comes next in the pattern Patterns - this video lesson explains patterns, and then gives your students the chance to show understanding on several quizzes. Spooky Sequences - One of the ghosts is missing a number. Click on the numbers along the bottom to enter the right number in the sequence. (square numbers) Spooky Sequences - One of the ghosts is missing a number. Click on the numbers along the bottom to enter the right number in the sequence. (triangular numbers) Spooky Sequences - One of the ghosts is missing a number. Click on the numbers along the bottom to enter the right number in the sequence. one digit numbers (by ones) | two digit numbers (by ones) | three digit numbers (by ones) | counting by twos | counting by fives | counting by tens | backward by ones | backward by twos | backward by fives | backward by tens What Comes Next? - study repeating patterns and click on the one that continues the pattern (B)  identify patterns in multiplication facts using concrete objects, pictorial models, or technology Create your own pattern - drag shapes to create a pattern (Instructions on how to use this page in your classroom) Early Algebra Worksheet - Use the scales to find the weight of the shapes. Same shapes weigh the same amount. Early Algebra Worksheet 2 - Use the scales to find the weight of the objects. Same shapes weigh the same amount. What comes next? - find the next shape in the pattern (C)  identify patterns in related multiplication and division sentences (fact families) such as 2 x 3 = 6, 3 x 2 = 6, 6 ¸ 2 = 3, 6 ¸ 3 = 2 (3.7) The student uses lists, tables, and charts to express patterns and relationships. (A)  generate a table of paired numbers based on a real-life situation such as insects and legs (B)  identify and describe patterns in a table of related number pairs based on a meaningful problem and extend the table National Library of Virtual Manipulatives Algebra (Grades 3 - 5)

 Geometry & Spatial Reasoning (3.8)   The student uses formal geometric vocabulary. identify, classify, and describe two- and three-dimensional geometric figures by their attributes. The student compares two- dimensional figures, three-dimensional figures, or both by their attributes using formal geometry vocabulary Anglemania - [this link opens on a new page] Students describe triangles using appropriate geometric vocabulary. (Author - Laurie Ayers) Identify Polygons - names of polygons by number of sides and angles Name that Polygon - identify name of given polygon components Patterns for Solid Figures - Complete to make a cube figure Quad Squad - [this link opens on a new page] Students describe various quadrilaterals. (Author - Sandi King) Shape, Space and Measure - activities, quizzes and more Solid Pattern Pieces - [this link opens on a new page] Students name the different faces of solid figures to make objects using a pattern. (Author - Paulette Boggs) Triangle Identification - what type of triangle is it given its angles Triangle Identification - what type of triangle is it given its number of sides (3.9)   The student recognizes congruence and symmetry. (A)  identify congruent two-dimensional figures Congruent Concentration - [this link opens on a new page] Students use a matching board to demonstrate knowledge of congruent figures. (Author - Paulette Boggs) Congruent or Not - [this link opens on a new page] Students explore the concept on congruency of polygons. (Author - Randy Russell) (B)  create two-dimensional figures with lines of symmetry using concrete models and technology (C)  identify lines of symmetry in two-dimensional geometric figures Lines of Symmetry - this video lesson explains horizontal, vertical and diagonal line symmetry, and then gives your students the chance to show understanding on several quizzes. (3.10)   The student recognizes that a line can be used to represent numbers and fractions and their properties and relationships. locate and name points on a number line using whole numbers and fractions, including halves and fourths Decimal Darts - [game for one or two players] an invisible number line is superimposed on a dart board, students calculate the location of a balloon and then throw a dart Decimal Number Line - Identify and estimate decimal fractions on a number line. Move the pointer along the line, find a number between two others by looking at the next decimal place. Click on “Use the decimal number lines tool” at the bottom of the page. Decimal Speedway - [game for one or two players] the number line is in the form of a race track, students must multiply decimals and then locate the correct point on the track (number line) Estimate numbers on a number line - after students make their estimate you reveal the answer and display a new problem. Worksheet Generator - Print your own number line worksheets, you decide on the starting and ending numbers and the increment. National Library of Virtual Manipulatives Geometry (Grades 3 - 5)
