This is designed to be 10 puzzle pieces (numbers 0 through 9) that fall through the plate and into the container below.
In the United States, the Child Safety Protection Act requires warning labels on packaging for toys containing small parts. A tool called the small parts test fixture is used to measure toy parts. It is a cylinder tube that is 1.25 inches in diameter and between 1 and 2.25 inches deep. It is designed to mimic a child's mouth and pharynx. Any object that fits in the tube is considered a small part and must have a label on its packaging indicating it is a choking hazard for small children.
This 3D object at its current scale (in inches) contains small parts. The puzzle may be scaled larger but is currently designed for a 3D print bed with dimensions not quite 9in by 9in. The usable dimensions are 6in by 6in. If you have a larger printable area and would prefer to give this toy to a child younger than 3 years, please scale the design appropriately.
Also Note: I do not recommend the lesson plan below for very young children; even if it were developmentally appropriate the use of small beads, buttons, or base ten counting blocks also presents a choking hazard.
I experimented with a different stand/box combination. The plate and stand are one piece and the drawer is separate.
I used the Dyslexie font because it is easier for children and adults with dyslexia to read without flipping or switching digits.
Overview and Background
Understand the relationship between numbers and quantities; connect counting to cardinality.
When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
Lesson Plan and Activity
Count to tell the number of objects.
Today, we are going to look carefully at numerals. You will count from zero to nine and identify that quantity of [something] as you put the numeral into its matching hole. (Allow the student to trace the numerals with their fingers.)
Play What’s in the Bag? Place the numeral pieces in a sock or small bag. The student must choose a numeral by feel alone. The student reaches in the bag and finds one numeral. Your student must identify the number without looking and then withdraw the piece to check. After the student has confirmed the numeral they are holding they must put together the same number of [something], to show the quantity that numeral represents. Alternatively, the teacher names a numeral or presents a quantity of [something] and asks the student to withdraw that numeral without looking.
