Illustrations and Key Ideas is a free printable Grade 1 English worksheet on using pictures and details together to explain the ideas, aligned to Common Core standard RI.1.7. It prints 2 questions with an answer key on its own sheet of paper, in 25 versions, 24 of them with different questions, so no two pupils in the class work from the same page. Print it from the browser or download it as a PDF — no account, no email.
Set 15 of 25 · the same problems every time you open this link.
Set 1 has all 25 in a single PDF. 24 of these 25 sets ask different questions — this skill does not have 25 questions to give. The rest reorder them, so no two pupils have the same paper in front of them.

How a Bridge Stands Up
A bridge has to hold its own weight and the weight of everything crossing it.
The simplest bridge is a beam: a flat piece laid across a gap. A beam bridge cannot be very long, or it sags in the middle.
An arch bridge is curved. The curve pushes the weight out to the ends, where the ground is solid. That is why arch bridges can cross wider gaps.

Why Tall Buildings Do Not Fall Over
A tall building needs a wide, deep base. The base is called a foundation. It spreads the weight into the ground.
Wind pushes hard on a tall building. Inside, a strong core of concrete runs from the bottom to the top like a spine. The core stops the building bending too far.
The tallest buildings sway a little in strong wind. That is meant to happen. A building that could not bend at all would crack.

Answer key — Illustrations and Key Ideas
Set 15. Prints on its own sheet.
1.1. A flat beam bridge and a curved arch bridge side by side. 2. Different bridge shapes hold weight in different ways.
2.1. Tall buildings stay up because of a wide foundation and a strong core, and because they can bend a little. 2. The foundation at the bottom and the concrete core running up the middle.
