Comparing Sizes and Amounts

Comparing Sizes and Amounts Worksheet: Scale, size, and amount (Grade 4 Science, TEKS 4.5C)

Students compare animal lengths in a table, decide if a museum model ant is smaller or bigger than a real ant, and compare the rain in two Texas cities using which is more and how much more. The page teaches the idea first, so no prior lesson is needed, and every answer is on the page.

What's Inside

• A teach box that defines a model, scale, and amount, with a toy car example
• Part A: an animal length table and a model ant question
• Part B: a rainfall table for Houston and El Paso
• A raccoon guide with a hint that matches the answer key
• An answer key with answers marked in red, plus a short teacher note with what to watch for

How Teachers Use It

Read the teach box and the worked example together, then let students try Part A and Part B. It takes 8 to 10 minutes and prints clearly in black and white. The focus skill is using scale and amounts to compare, part of TEKS 4.5C: use scale, proportion, and quantity to describe, compare, or model different systems.

Why It Works

Each sheet uses familiar things like plants, bikes, ice, and food chains, so the big idea is easy to see. Questions are short, mostly circle or one line answers, and the reasoning is on the teacher key. Pair it with the other seven Grade 4 Big Ideas in Science sheets to cover patterns, cause and effect, scale, systems, energy and matter, structure and function, and stability and change.
