What kinds of problems are on the first grade sheet?

Three types take turns: circle the word for the shares shown (halves or fourths), say yes or no to whether a rectangle's shares are equal, and count how many equal shares a shape has.

Why do some shapes show unfair cuts?

Because the standard asks kids to know what equal shares are, and the fastest test of that is spotting shares that aren't. An off-center cut makes two pieces, but not halves.

The kind of problems you'll get

Count the parts. Tell whether they are equal. Name the equal shares, or write unequal parts.

A whole is split into four equal parts. What is one part called?
Answer: One fourth, or one quarter.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

How to teach this

Food is the fastest way in. Fold a paper "sandwich" and ask whether both kids would be happy with their piece. On the yes/no items, have your child point to the bigger piece before answering; if they can find a bigger piece, the shares aren't equal. Keep the words precise: two equal pieces are halves, four equal pieces are fourths, and unequal pieces are just pieces.

Watch for: Kids call any two parts halves. Halves must be the same size, so an off-center cut makes two unequal parts, not halves. Kids think more shares means bigger shares. Cutting the same shape into more pieces makes each piece smaller, so fourths are smaller than halves.
