  2. Thank you Lisa! I hope the new video helps. Another perspective would be the

    Decimal perspective:

    3/4 is like 3 quarters =.75
    1/10 is .10
    .75+.10=.85
    .85=85/100 or 17/20
    The connection to money often helps the kids.

    The common denominator approach:
    fourths and tenths can easily be viewed as 20ths
    3/4 would be 15/20
    1/10 would be 2/20
    15/20+2/20=17/20
