October 31- November 4
We are currently working on Unit 2 and Module 4.
In this unit students will:
• cultivate an understanding of how addition and subtraction affect quantities and are related to each other
• will reinforce the multiple meanings for addition (combine, join, and count on) and subtraction (take away, remove, count back, and compare)
• further develop their understanding of the relationships between addition and subtraction
• recognize how the digits 0-9 are used in our place value system to create numbers and manipulate amounts
• continue to develop their understanding solving problems with money
• At the beginning of Unit 2, it is recommended that students practice counting money collections daily during Number Corner or as part of daily Math Maintenance in order to be prepared for the tasks. For more detailed information regarding unpacking the content standards, unpacking a task, math routines and rituals, maintenance activities and more, please refer to the grade level overview.
These are our focus standards:
Represent and solve problems involving addition and subtraction.
MGSE2.OA.1 Use addition and subtraction within 100 to solve one and two step word problems by using drawings and equations with a symbol for the unknown number to represent the problem. Problems include contexts that involve adding to, taking from, putting together/taking apart (part/part/whole) and comparing with unknowns in all positions.
Add and subtract within 20.
MGSE2.OA.2 Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
Use place value understanding and properties of operations to add and subtract.
MGSE2.NBT.5 Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Work with time and money.
MGSE2.MD.8 Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?
MGSE2.MD.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph
