3. Goals: Aims/Outcomes-
|
1.Students will fluently add and subtract with 100 using strategies
based on place value, properties of operations, and /or the relationship
between addition and subtraction. 2.NBT.5
2.Students will use addition and subtraction within 100 to solve one-
and two-step word problems involving situations of adding to, taking
from, putting together, taking apart, and comparing, with unknowns
in all positions, eg, by using drawings and equations with a symbol
for the unknown number to represent the problem. Second grade's variable
is "s".

6. Procedures/Methods-
|
|
A. Introduction-
1.Students will use Base Ten Blocks and make pictures of Base Ten
Blocks of showing a number in two ways (eg, 84+ 8 tens and 4 ones
and 7 tens and 14 ones.
2.Students will subtract 1 digit from two digit numbers with regrouping.
|
| |
|
|
B. Development-
1. Manipulatives such as counters, Base Ten Blocks, and playing
cards with beans as counters will be employed.
2. Teacher will model using Base Ten Blocks, counters, and playing
cards with beans so that students will understand that when you regroup,
you gather ten ones to make a ten or break apart a ten into ten ones.
Using base ten blocks and counters to model number sentences and practice
regrouping. |

|
|
C. Practice-
1. Students will use manipulatives so that they will have a clear
understanding of when you regroup, you gather ten ones and trade it
in for a ten. Also, take a ten and trade it for ten ones.
2. Workmat from textbook.
