## Weekly Overview

Weekly Topics

The focus of this week’s instruction is to deepen students’ understanding of:

• Solve word problems involving the total value of a group of bills.
• Solve word problems involving different combinations of coins with the same total value.
• Solve two-step word problems involving dollars or cents with totals within $100 or$1.
• Solve two-digit addition and subtraction word problems involving length by using tape diagrams and writing equations to represent the problem.
• Represent two-digit sums and differences involving length by using the ruler as a number line.

Materials Needed

• Student Print Packets for each day
• End of Week Assessment
• Dry erase board with markers
• Money (bills and coins)
• Open Number Lines

Standards Covered

2.MD.B.5 Add and subtract within 100 to solve contextual problems involving lengths that are given in the same units by using drawings and equations with a symbol for the unknown to represent the problem.

2.MD.B.6 Represent whole numbers as lengths from 0 on a number line and know that the points corresponding to the numbers on the number line are equally spaced. Use a number line to represent whole number sums and differences of lengths within 100.

2.MD.C.8 Solve contextual problems involving dollar bills, quarters, dimes, nickels, and pennies using ¢ and $symbols appropriately. 2.NBT.A.2 Count within 1000. Skip-count within 1000 by 5s, 10s, and 100s, starting from any number in its skip counting sequence. 2.NBT.A.4 Compare two three-digit numbers based on the meanings of the digits in each place and use the symbols >, =, and < to show the relationship. 2.NBT.B.5 Fluently add and subtract within 100 using properties of operations, strategies based on place value, and/or the relationship between addition and subtraction. 2.NBT.B.6 Add up to four two-digit numbers using properties of operations and strategies based on place value.
