Next, we will learn about number value. We will learn how to count objects in groups and name the numbers for different groups of objects. We will also learn how to compare the quantities of two groups of objects and determine the number values up to 100. We will practice showing the quantity of a given number, matching groups of objects with their numbers, and comparing the value of two numbers. Additionally, we will learn how to write numbers in numerals and words. Finally, we will learn about combinations of one-digit numbers.
