Which of the following is considered a manipulative in math instruction?

Manipulatives in math instruction are physical objects that students can use to model and understand mathematical concepts. They provide a tangible way for learners to engage with abstract ideas, making math more relatable and easier to comprehend.

In the context of this question, options like pencil and paper, computers and tablets, and worksheets are primarily tools for recording or practicing mathematical concepts rather than hands-on learning aids. They do not provide the interactive and tactile experiences that manipulatives offer.

On the other hand, items such as dice, money, cards, or dominoes are considered manipulatives because they allow students to physically manipulate the objects to explore mathematical ideas. For example, dice can be used to teach probability, money can help with understanding value and making change, and cards or dominoes can assist in teaching counting, patterns, or operations in a visually engaging way. This hands-on approach can enhance understanding and retention of math concepts, making this option the correct answer.
