Lesson 56: Solve Equations Involving Numbers Up to 10

Directions

Follow the step-by-step instructions below to teach the lesson.

Children progress to Ray's Primary Arithmetic (first grade math) when they master the current lesson to the instructor's satisfaction.

Value mastery over speed of progression.

Steps

STEP 1

Have children recite and solve each equation listed below.

STEP 2

Have children copy on paper the equations listed below and their solutions.

EQUATIONS

• 9+1 or 1+9= ; therefore 10-1= ; 10-9=
• 8+2 or 2+8= ; therefore 10-2= ; 10-8=
• 7+3 or 3+7= ; therefore 10-3= ; 10-7=
• 6+4 or 4+6= ; therefore 10-4= ; 10-6=
• 5+5= ; therefore 10-5=

Repeat this lesson every day until children can easily recite and write the equations and their solutions.
