MATH:
Adding and Subtracting Whole Numbers
Unit 2 will focus on addition and subtraction of whole numbers, emphasizing problem solving strategies and computational skills. In Second Grade Everyday Mathematics, children used shortcuts, fact families, Fact Triangles, and games to help them learn basic addition and subtraction facts. Such devices will continue to be used in third grade. Knowledge of the basic facts and their extensions is important. Knowing that 6 + 8 = 14, for example, makes it easy to solve such problems as 56 + 8 = ? and 60 + 80 = ? Later, knowing that 5 × 6 = 30 will make it easy to solve 5 × 60 = ?, 50 × 60 = ?, and so on.
Vocabulary:
- ballpark estimate A rough estimate. A ballpark estimate can be used when you don’t need an exact answer or to check if an answer makes sense.
- function machine an imaginary machine that processes numbers and pairs them with output numbers according to a set rule. A number (input) is put into the machine and is transformed into a second number (output) through the application of the rule.
- fact family A collection of 4 related addition and subtraction facts, or multiplication and division facts, relating 3 numbers.
- function machine an imaginary machine that processes numbers and pairs them with output numbers according to a set rule
-
- number family Same as a fact family
- number model A number sentence that shows how the parts of a number story are related. For example, 5 + 8 = ?
- models the number story: 5 children skating. 8 children playing ball. How many children in all?
- parts-and-total diagram A diagram used to represent problems in which two or more quantities are combined to form a total quantity
- change diagram A diagram used to represent addition or subtraction problems in which a given quantity is increased or decreased. The diagram includes the starting quantity, the ending quantity, and the amount of the change.
- comparison diagram A diagram used to represent problems in which two quantities are given and then compared to find how much more or less one quantity is than the other. For example, the comparison diagram here represents this problem: 34 children ride the bus to school. 12 children walk to school. How many more children ride the bus?
- unit box In Everyday Mathematics, a box displaying the unit for numbers in the problems at hand
SOCIAL STUDIES
Over the next two weeks, students will finish their migration stories and begin presenting their migration stories on Google Slides. The Migration Analysis document will help students complete their Google Slide presentation. Please help your child complete this document. As well as learning valuable map skills and historical content, students are learning valuable technology skills as they complete their presentation. Here is the rubric that will be used to assess student work for this unit.
Language Arts
We are pleased to announce that our Reading and Writing Workshops are underway and the students are now familiar with the processes used for building stronger reading and writing lives. They are now working effectively throughout the sessions. Please continue to support your child's at home reading and completion of the logs.
In addition, all classes have implemented a word study program that requires your child to study word patterns appropriate for his or her spelling level. Your child will be required to complete one spelling assignment for homework each week.
Lastly, we encourage parents to take advantage of the many resources available in the Lower School Library. Parents are welcome to check out books to supplement their at-home libraries.
Your support is always appreciated.
