This math chapter workbook on "Addition and Subtraction to 100" engages students with various problems designed to build their foundational skills for adding and subtracting numbers with sums and differences of up to a hundred. For example, students might solve simple addition problems, such as 23 + 15, by aligning numbers vertically and adding ones and tens separately, reinforcing place value comprehension. Similarly, for subtraction, problems like 47 - 19 can help students practice regrouping, where they learn to 'borrow' from the tens place when the top number is smaller than the bottom number in a column. Word problems are included, such as, "Emma has 36 apples, and she gives 14 to her friend. How many apples does she have left?" to help students apply addition and subtraction in real-world contexts.
