Start at the first number. Jump right to add, left to subtract, as far as the second number. Where you land is the answer.
number linea line with numbers at equal spaces
jumpa move along the line
ticka small mark on the line
equationa number sentence with an equals sign
Watch for: Counting the ticks as 1 each when they count by 5s or 10s. Jumping right for a subtraction. Starting the jump at 0 instead of the first number.
At home: Draw a line marked 0 to 100 by tens on paper. Take turns making jumps with a toy and saying the equation.
