# Q1W5 (9/13 – 9/17)

Teacher Kathleen Manning Math and Science 4 5 Add/Subtract Multi-Digit Numbers; Earth's Patterns and Space
Standard(s) Taught

MATH: MAFS.4.NBT.2.4
– Fluently add and subtract multi-digit whole numbers using the standard algorithm.

SCIENCE: SC.4.E.5.1 5.2
– Observe that the patterns of stars in the sky stay the same although they appear to shift across the sky nightly,
and different stars can be seen in different seasons.

Learning Targets and Learning Criteria

The student will:
– Apply an understanding of addition and subtraction, place value, and flexibility with multiple strategies to use the standard algorithms for addition and subtraction of whole numbers.
– Fluently add and subtract multi-digit whole numbers using the standard algorithm by the end of grade 4.
– Demonstrate that the star patterns (constellations) in the sky appear to shift across the sky nightly due to Earth’s rotation on its axis.
– Discuss how different star patterns are high in the night sky in some seasons but dip below the horizon in other seasons (summer sky vs winter sky).
– Explain that star patterns in the sky appear to move and change over the course of the year due to Earth’s revolution around the sun.
– Describe the changes that occur to the observable shape of the moon and record on a lunar calendar.
