- Yuki's glue sticks keep rolling off the table. She sketches a holder that is a rectangle with four circle openings on top. She draws glue sticks standing in the circles. The holder has a flat bottom. Which shape feature is important for solving the problem?
Answer: The circle openings hold glue sticks so they stay put.
This question tests the 1st grade skill of developing a simple sketch to show a solution to a problem, focusing on how the object's shape helps it function (K-2-ETS1-2: Develop a simple sketch to illustrate how the shape of an object helps it function as needed to solve a given problem). When designing solutions to problems, we sketch or draw our ideas to show what we're thinking. An important part of any design sketch is showing the shape of the solution and how that shape helps solve the problem. Different shapes do different jobs: flat shapes provide surfaces to place or stand on; shapes with edges or walls hold things in and prevent spilling or falling; shapes with dividers separate items into sections; round shapes roll or don't have corners; narrow shapes fit in tight spaces; wide shapes are stable. A good sketch shows the shape features that are important for making the solution work. In this scenario, Yuki's glue sticks keep rolling off the table. Yuki sketched a solution showing a holder that is a rectangle with four circle openings on top. The key shape features shown are circle openings that are sized to hold glue sticks upright and a flat bottom for stability. Choice A is correct because it accurately identifies the shape: describes the circle openings shown in sketch; correctly connects shape to function: explains how circles hold glue sticks in place; identifies key functional feature: focuses on the openings that prevent rolling. For example, the circle openings create specific spots where glue sticks can stand upright, preventing them from rolling away like they do when loose on the table. Choice D represents decorative focus. This error typically occurs when students notice shape but don't connect it to function, thinking the circles are just for decoration rather than understanding that the circular shape fits around the glue sticks to hold them steady and prevent rolling. To help students understand sketching solutions: Practice 'shape does job' connections (flat top - stand on it, edges - hold things in, dividers - separate items, holes - hold specific things, wide base - stable); have students sketch simple solutions and explain 'how does this shape help?'; look at real objects and identify functional shape features; emphasize that sketch should show the shape features that make it work, not just be pretty. Watch for: students who draw but can't explain how shape helps, who focus on decorative elements instead of functional shape, who describe shape without connecting to problem-solving, who miss the key functional feature in their description, or who think any shape will work without thinking about what shapes do. Key concept: the SHAPE of an object determines what it can do - we sketch to show and communicate what shape we need to solve the problem.
- Carlos keeps dropping his glue and scissors when he carries them. He sketches a tray shaped like a rectangle with raised edges and a small handle. He draws the handle as a curved line on one side. The edges are drawn tall around the tray. The sketch shows items staying inside while he holds it. How does the shape in the drawing help solve the problem?
Answer: The raised edges help keep items from falling off.

Carlos sketched a solution showing a rectangle tray with raised edges drawn tall around the tray and a curved handle on one side. The key shape features shown are the raised edges that create barriers to keep items from falling. Choice A is correct because it accurately identifies that the raised edges help keep items from falling off, which directly solves Carlos's dropping problem. For example, the tall edges around the tray create walls that prevent glue and scissors from sliding off when Carlos carries the tray. Choice B represents the aesthetic reasoning error - focusing on colors helping items stay rather than the functional shape. This error typically occurs when students attribute function to non-functional features like color instead of understanding how shape creates function.

Jamal sketched a solution showing platform with wide flat top and stable base. The key shape features shown are flat top surface to stand on. Choice A is correct because it accurately identifies the shape: describes the shape shown in sketch; correctly connects shape to function: explains how shape feature solves problem; identifies key functional feature: focuses on the shape element that makes solution work. For example, the flat top provides a stable surface to stand on to reach high items. Choice C represents error type: decorative focus.

- Amir spills juice when he pours into a small bottle. He sketches a funnel with a wide top opening and a narrow bottom opening. He draws the top as a big circle and the bottom as a small circle, with slanted lines between. He adds an arrow showing liquid going down. The sketch shows the shape getting smaller. How does the shape in the drawing help solve the problem?
Answer: The wide top guides liquid into the narrow opening.

Amir sketched a solution showing a funnel with a wide top opening (big circle) and a narrow bottom opening (small circle) with slanted lines between. The key shape features shown are the wide top narrowing to a small bottom, creating a funnel shape. Choice A is correct because it accurately identifies that the wide top guides liquid into the narrow opening, which directly solves Amir's spilling problem. For example, the wide top catches the juice and the narrowing shape guides it down into the small bottle opening without spilling. Choice B represents the wrong shape feature error - describing divider lines that aren't in this sketch. This error typically occurs when students confuse different solutions or don't carefully observe what shape is actually drawn.

Answer: The wide top catches water and the narrow bottom guides it in.
This question tests the 1st grade skill of developing a simple sketch to show a solution to a problem, focusing on how the object's shape helps it function (K-2-ETS1-2: Develop a simple sketch to illustrate how the shape of an object helps it function as needed to solve a given problem). When designing solutions to problems, we sketch or draw our ideas to show what we're thinking. An important part of any design sketch is showing the shape of the solution and how that shape helps solve the problem. Different shapes do different jobs: flat shapes provide surfaces to place or stand on; shapes with edges or walls hold things in and prevent spilling or falling; shapes with dividers separate items into sections; round shapes roll or don't have corners; narrow shapes fit in tight spaces; wide shapes are stable. A good sketch shows the shape features that are important for making the solution work. In this scenario, Amir spills when pouring water into a small bottle. His sketch shows a funnel with a wide top and a narrow bottom and arrows going down. The key shape features shown are wide top narrowing to point. Choice A is correct because it accurately identifies the shape: describes the shape shown in sketch; correctly connects shape to function: explains how shape feature solves problem; identifies key functional feature: focuses on the shape element that makes solution work. For example, the wide top catches water and the narrow bottom guides it in. Choice B represents wrong shape feature: describes the shape incorrectly, like bottom is wide so water sprays out. This error typically occurs when students notice shape but don't connect it to function, focus on non-functional aspects of drawing, miss the key shape feature that solves problem, confuse what shape does, describe general shape without explaining how it helps, think any shape description is sufficient. To help students understand sketching solutions: Practice 'shape does job' connections (flat top - stand on it, edges - hold things in, dividers - separate items, holes - hold specific things, wide base - stable); have students sketch simple solutions and explain 'how does this shape help?'; look at real objects and identify functional shape features; emphasize that sketch should show the shape features that make it work, not just be pretty. Watch for: students who draw but can't explain how shape helps, who focus on decorative elements instead of functional shape, who describe shape without connecting to problem-solving, who miss the key functional feature in their description, or who think any shape will work without thinking about what shapes do.

- Sofia's markers keep rolling off her desk and onto the floor. She sketches a holder shaped like a long rectangle with five round holes on top. She draws circles for the holes and writes "holes" with an arrow. The holder has straight sides and a flat bottom. The round holes are the main shape feature in her drawing. How will the holes help?
Answer: The holes hold the markers so they do not roll.

- Keisha spills when pouring sand into a small jar. She sketches a funnel shape with a wide opening at the top and a narrow tube at the bottom. She draws sand going down with an arrow. The funnel has slanted sides. Which part of the shape helps solve the problem?
Answer: The wide opening catches sand and sends it into the jar.

A good sketch shows the shape features that are important for making the solution work. In this scenario, Keisha spills when pouring sand into a small jar. Keisha sketched a solution showing a funnel shape with a wide opening at the top and a narrow tube at the bottom. The key shape features shown are a wide opening to catch sand easily and slanted sides that guide sand down to the narrow bottom. Choice A is correct because it accurately identifies the shape: describes the wide opening shown in sketch; correctly connects shape to function: explains how wide opening catches and guides sand; identifies key functional feature: focuses on the wide top that makes pouring easier. For example, the wide opening gives Keisha a bigger target to pour sand into, and the funnel shape guides the sand down through the narrow tube into the jar without spilling. Choice D represents aesthetic reasoning. This error typically occurs when students think any shape description is sufficient, focusing on how something looks (cool and shiny) rather than understanding that the funnel shape with wide opening specifically helps catch and guide sand into a small jar opening.
