Dinosaur Island Sums

Worksheet Description

The worksheet is a math exercise sheet that presents a series of two-digit addition problems for students to solve, employing the regrouping technique. The problems are laid out in a columnar form which is the standard format for teaching regrouping, as it allows students to clearly see when the sum of the ones place exceeds nine and carrying over to the tens place is needed. The worksheet is decorated with line drawings of playful dinosaurs in a prehistoric setting, which students can color in, making the task more enjoyable. The layout is thoughtfully designed to mix the analytical task of addition with the creative task of coloring.

The purpose of this worksheet is to reinforce the student’s ability to add two-digit numbers and understand the concept of regrouping, a fundamental math skill. It guides them through adding the ones column first, carrying over any tens, and then adding the tens column. By practicing these steps, students solidify their grasp of basic addition and prepare for more advanced arithmetic. The inclusion of a coloring activity also encourages students to associate math practice with a positive and rewarding experience.
