Which of the following is the most appropriate way to teach the concept of comparing numbers and quantities to first-grade students with learning disabilities?

• A. Providing the students a set of three-digit numbers to arrange in ascending order
• B. Providing the students with worksheets in which they have to use symbols to identify greater than and less than
• C. Providing the students with base-ten blocks that they must use to create representations of two given numbers and identify the larger number
• D. Providing the students with a word problem in which they have to compare the population of two countries using Internet resources

Answer: (C)

Connecting numbers to concrete quantities helps learners determine which is larger. For first-grade students with learning disabilities, using manipulatives makes this abstract idea tangible and builds solid number sense. Base-ten blocks let students represent each number with tens rods and ones cubes, so they can physically compare two quantities. When they create both numbers, they can see and count how many tens and how many ones each has, and then decide which is bigger. If one number has more tens, it’s larger; if the tens are the same, the number with more ones is larger. This approach supports place-value understanding and gives immediate, visual feedback, which is especially helpful for students who struggle with abstract symbols.

Other methods jump ahead to symbols or rely on reading or online research, which can be challenging for learners at this level and may not directly build the necessary understanding of quantity and magnitude.
