MAFS.4.NBT.1.2, MAFS.4.NBT.1.3, MAFS.4.NBT.2.4
- Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
- Use place value understanding to round multi-digit whole numbers to any place.
- Add and subtract multi-digit whole numbers using the standard algorithm.

- Explain that models can be three-dimensional, two-dimensional, an explanation in your mind, or a computer model.
- Recognize that Earth revolves around the Sun in a year and rotates on its axis in a 24-hour day.
- Investigate how technology and tools help to extend the ability of humans to observe very small things and very large things.
- Relate that the rotation of Earth (day and night) and apparent movements of the sun, moon, and stars are connected.
- 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|
- Read and write multi-digit numbers through one million in base-ten numerals, number names, and expanded form.
- Compare two multi-digit numbers to 1,000,000 using place value and record the comparison numerically using the following symbols: <, >, or =.
- Use place value understanding to round multi-digit whole numbers (between 1,000 and 1,000,000) to any place.
- Understand that the purpose of rounding to estimate before adding or subtracting is to make mental math easier and to check the reasonableness of an answer.
- 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 with solutions greater than 1,000 and within 1,000,000.
- Explain that models can be three-dimensional, two-dimensional, a mental model (a picture in your mind), or a computer model.
- Use a model to demonstrate the difference between Earth’s rotation and Earth’s revolution.
- Explain that Earth rotates once on its axis in approximately a 24-hour period (day and night).
- Explain that Earth revolves (orbits) around the sun once in a year (approximately 365 days).
- Discuss the types of investigations in which a webcam, telescope, microscope, or hand lens might be used.
- Research the histories of the microscope and telescope reporting on what is learned.
- Identify the telescope and satellite as tools that have allowed scientists to see very large things, such as the Earth, the solar system, and parts of the universe.
- Review that the sun is the closest star to Earth.
- Demonstrate that the star patterns (constellations) in the sky appear to shift across the sky nightly due to Earth’s rotation.
- Discuss how different star patterns are high in the night sky in some seasons but dip below the horizon in other seasons (e.g., use models/ simulations of winter and summer skyline).
- Explain how the Earth’s movement causes the appearance of sun and star movement (tracking) across the sky.
- Explain that Earth’s rotation on its axis causes the sun/stars to appear as though they are moving across the sky.
