☀️ Scoot game for ten more and ten less

☀️ Two Capture 4 games

• Adding a multiple of 10 to a 2-digit number
• Subtracting a multiple of 10 from another multiple of 10

☀️ Themed 120 chart

☀️ Three partner games:

• Subtracting a multiple of 10 from another multiple of 10
• Adding a multiple of 10 to a 2-digit number
• Adding a 1-digit number to a 2-digit number

☀️ SEVEN printables for practice or assessment

### Standards

to see state-specific standards (only available in the US).
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
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.
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), 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.
