Goals
Unit Goals: |
To increase students’ awareness of place value; lining up numbers on their place value when adding & subtracting decimals & whole numbers. |
Students will understand the rules of
place values and be able to add and subtracting numbers involving ones, tens,
hundreds, and thousands.
|
Methods
Anticipatory Set: |
Keeping every student involved by randomly selecting someone to answer questions, demonstrating value placements with token and pennies, testing students, observing them solve problems and teaching them how to correct the questions that were not answered correctly. |
Introduce and Model New Knowledge: |
Students will be introduced to a new method of understanding place value by using tokens to model units, tens, hundreds and thousands; also by using fake money for adding and subtracting whole numbers and decimals. |
Provide Guided Practice: |
Place values will be demonstrated with different colors of tokens, fake pennies (for decimals). After demonstrations students will be observed while they identify how many ones, tens, hundreds, and thousands are in each stack of tokens and will be given numbers to subtract and add. Students will be shown how to correct their work if they got something wrong. |
Provide Independent Practice: |
Students will be given note cards with numbers, addition and subtraction questions, tokens and pennies; they will be asked to stack the tokens to fit the numbers on the cards and will need to follow directions on the cards. |
Assessment
Formative/Ongoing Assessment:
|
Students will be asked to play place value games on the computer which gives them a score of how many questions they answered right or wrong. This game will be dealing with adding and subtracting decimals and whole numbers, it will also include number placements. |
Students will be given 5
questions to answer dealing with number placements (units, tens, hundreds,
thousands) and subtraction & additions of whole numbers & decimals.
