Target 1​

Lesson Type:

New

Number Operation

:

Integer Composition

Understand that the digits in a four-digit number represent the amounts of thousands, hundreds, tens, and ones.

1:

Use a number to represent base ten block quantities.

2:

Represent a multi-digit number in expanded format.

3:

Represent the composition or decomposition of three-digit numbers with an addition equation (113 = 100+10+3 or 1 hundred 1 ten and 3 ones).

2nd

Vocabulary:

Place Value, Ones, Tens, Hundreds, Thousands, Expanded form, Standard form

Activities:

• Students wrote a given numeral.
• Students used base-ten blocks to represent the number.
• Students wrote a number in expanded form with an addition equation.    Home Exploration

Guiding Questions: Absent Students:

Target 2

:

1:

Understand why the standard algorithm for adding is based on place-value.

2:

Understand that when adding a multi-digit number, each place-value is being added individually to create the new sum (ones are added to ones, tens are added to tens, etc.)

3:

Understand that when adding a multi-digit number, to solve start in the lowest place-value and go left.

4:

Understand how to regroup based on place-value understandings (i.e., ten ones can be composed into one ten – ten tens can be composed into one hundred).

3rd

Vocabulary:

Activities:

• Students practiced solving addition problems using regrouping when necessary.
• Students played games where they solved addition equations using the standard algorithm to move across a game board.    Home Exploration

Guiding Questions: Target 3

:

1:

Understand and use 24-hour notation (military time).

2:

Link digital, analogy, a.m., p.m., and military time.

2nd

Vocabulary:

Analog, Digital, AM, PM, Military Time

Activities:

• Students were given activity cards with a digital time and determined if it occurred during the a.m. or p.m.
• Students were given a time on an analog clock, and wrote the time using a.m. or p.m., and using military time.    Home Exploration
