This is an interactive video site that takes students through the creation of tangrams, composing, and decomposing figures, and a variety of geometric vocabulary.
This site doesn't give practice in all types of subtraction problems, but it's great for fact practice. Kids have to answer facts and then try to outwit their opponent to get four in a row.
This site gives students a chance to explore place value through 100s by using composition and decomposition. This SLE is not addressed in Saxon.
This is a great site for helping kids understand place value through 100s using base 10 blocks. It would be great for a whole group lesson with the kids using base ten manipulatives or for small group work. This skill is not addressed in Saxon.
This activity can be tailored to either demonstrate a given value of money up to $1.00 using a variety of coin combinations ( M.13.2.5) or to demonstrate a given value of money up to $1.00 using the fewest coins possible (M.12.2.6). Neither is covered to mastery in Saxon.
Though this site lacks context, it gives students practice with addition/subtractions problems involving result, change, and beginning unknown.
This is an awesome resource for showing how addition and subtraction work on a number line. Things to stress might include that moving from left to right shows addition and the opposite for subtraction. Most importantly, subtraction can be seen as the distance between the two numbers no matter the type of problem.
This interactive video lesson is a great resource for teaching and practicing repeating patterns. There are many connections to patterns in nature.
This interactive site lets you set the intervals for counting and then follow a path.

This is a great site for demonstrating and practice with adding and subtracting. By allowing kids to move forward and backward by ones, fives, and tens, it's great practice with composing and decomposing numbers.
This site allows students to practice comparing numbers in standard form using the < and > symbols and can be set for a variety of number lenghts for differentiation. Note that before they're ready for this symbolic practice, students will need lots of practice with modeling and pictures.
This site offers opportunities to count combinations of pennies, nickels, and dimes. It would be a good resource for intervention before adding quarters.
Great site for skip counting by numbers 1-9. Note that after the first few games the numbers aren't always multiples of the number chosen.
This site is awesome for practicing different addition types with kids. It lacks context, so you may want to make up stories to go with the problems. The fact that there's a built in number line is priceless.
This site allows you to create worksheets with options that will allow you to differentiate your lesson.
