From site:
Worksheet Library was developed and is maintained by veteran elementary teachers who have over 50 years of classroom experience – and climbing every year. Like you, we get up every school day and greet our students with their bright shiny faces. In fact, that smile is what keeps us going. Knowing that we help shape the future makes us proud. But being proud does not get our work done. Worksheet Library is here to help with some of that workload.
We develop each worksheet of our site with the goal of making it clear and simple. We want to help you reduce your planning time and spend more quality time with your students.
We serve K-6 teachers exclusively, because we are K-6 teachers who know exactly what you are going through. This is why our worksheets are preformatted and ready to use in your classroom. Once you find the exact worksheet you need, it is ready to print. We also provide a simple answer key for any worksheet that needs one.
