# Q1W4 (9/7 – 9/10)

Weekly-Assignments-Sept. 7-Sept.10

Teacher Kathleen Manning Math and Science 4 4 Rounding; Add/Subtract Multi-Digit Numbers; Earth's Patterns and Space
Standard(s) Taught

MATH: MAFS.4.NBT.1.3 2.4

– Use place value understanding to round multi-digit whole numbers to any place.
– Fluently add and subtract multi-digit numbers using the standard algorithm.

SCIENCE: SC.4.E.S.2 S.4

– Describe the changes in the observable shape of the moon over the course of about a month.
– Relate that the rotation of Earth (day and night) and apparent movements of the sun, moon, and stars are connected.

Learning Targets and Learning Criteria

The student will:

– Understand that the purpose of rounding to estimate “before an operation” is to make mental math easier and to
check the reasonableness of an answer.
– Use place value understanding to round multi-digit whole numbers (between 1,000 and 1,000,000) to any place.
– Describe the changes (patterns) that occur to the observable shape of the moon over the course of about a month
that have been recorded on a moon calendar sheet.
– Sequence moon patterns
– Explain that the moon’s physical shape does not actually change.
– Review that the sun is the closest star to Earth.
– Explain that Earth’s rotation on its axis causes the sun to appear as it is rising, moving across the sky, and
setting each day.
– Explain that Earth’s rotation on its axis causes the stars to appear as though they are moving across the sky each
night.
