Longview ISD 2nd Grade Math Unit 4-4
2nd Grade TEKS with Specificities:2.6 Patterns, relationships, and algebraic thinking. The student uses patterns to describe relationships and make predictions. The student is expected to:
2.6A Generate a list of paired numbers based on a real-life situation such as number of tricycles related to number of wheels.
2.6B Identify patterns in a list of related number pairs based on a real-life situation and extend the list.
· Example - give students a graph that includes teddy bears that have 2 ears. Two teddy bears would have 4 ears, etc. Students create a list of number pairs, describe the pattern and extend by creating the next row.
Note:
This is the first time students extend patterns using numbers.
2.6C identify, describe and extend repeating and additive patterns to make predictions and solve problems
· Example - repeating and growing patterns using pictures of bugs, animals, or other real objects, geometric shapes, numbers or beads
· Repeated addition of the same number produces a growing pattern - ex. counting legs in bugs, one bug 6 legs, two bugs 6 + 6 = 12 legs etc. / Unit 4
