observe Lists of similarities/differences created
◦Similarities

‣ Heavy/light
‣ Size
‣ Weight
Talking about equals...
◦Imagine a teeter totter - who would be on
the down side, me or you? Which ball would
be on the downside?
◦We're going to talk about what equals means. ◦And we're going to talk about weight. Think about the symbol = and think about what
it might mean
◦Turn and talk
◦Slow me with your hands your teeter totter
and what equals means. Balancing Act • What do you think the mice might be
doing? What might be your inference?
◦Getting ideas from the children • There's that word "balance"
• Balance = TA DA!
• One mouse goes into the scale - how do
we make it equal?
one metal, one ping pong
Feeling the difference in weight
Creating a hand scale
• Show me equals with your hands...
• "They're both the same" - same as
• Predicting what comes next to make things
equal - to make things balanced?
• How does one bird equal six animals?
◦Turn and talk
Using hands as a balance
Use of scale to represent each animal.
◦If each animal weighed 6g, how much
would the bird weigh?
Adding another animal to the scale
• Lets build a teeter totter! Board work • When you go and try - try on your card, then verify on scale.
