Addition word problems up to 10

Addition word problems up to 10: a free Grade 1 math game for ages 6-7. Each round draws 8 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

A farmer sells sheep two weeks running, a hen's eggs hatch at morning and evening, birds peck and fly on the way to school. Addition word problems up to 10 gathers 32 such stories, and eight make a Grade 1 round. Each story is read aloud; your child finds the two amounts and taps the total from six numbers in a row. Every answer is checked and explained as a sentence, such as 7 + 3 = 10.

Word problems ask for the step before the arithmetic: hearing which numbers matter and that in all means joining them. These stories vary the setting, the time and even the kind of thing, bowls and dishes, cats and puppies, so your child learns that the action, not the objects, decides the operation. Some stories hide a zero: no eggs hatch in the morning.

Six choices sit in a row, and one of the story's own numbers is often among them: 7 for 7 girls and 3 boys, 5 for 5 tomatoes and 3 more. Grabbing the bigger number is tempting. Ask, "Who else is in the story?" Praise the full reading: "You found both numbers before you added."

  • 1.NBT.C.4 Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
  • 1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
