Adding whole hundreds - Exercise 1

This worksheet is designed for first graders to practice adding whole hundreds, a fundamental skill that strengthens their understanding of place value. Students will find a series of addition problems involving whole hundreds, such as 800 + 300 and 600 + 400, helping them see how numbers combine and grow. This is a great activity for reinforcing number sense in a fun way. Consider using it as a quick math warm-up or an independent practice session, and encourage students to use manipulatives or drawings to visualize the sums for deeper understanding.
