Our math program is called Learn Zillion. It has been adopted by the 4j District in 2017. It is aligned with Common Core Standards.

You can find the website at this link: LearnZillion.

Mental math strategies to review at home. the kids know the names in French. :)

#1 Décomposer (decomposing)

32 + 45 =

30 + 40 = 70 (tens)

2 + 5 = 7 (ones)

70 + 7 = 77

45 - 32 =

40 - 30 = 10

5 - 2 = 3

10 + 3 (because we put together 10 and 3) = 13

#2: Grille de 100 (hundred chart) We decompose the 2nd addend.

42 + 35 =

42 + 30 = 72

72 + 5 =77

42 - 35 = This is to be used when we CANT use strategy #1 with the ones (we can't do 2-5...)

42 - 30 = 12

12 - 5 = 7

#3 A la dizaine (go to a ten-it's also compensation)

49 + 32 =

50 + 32 = 82

82 -1 = 81

or 50 + 31 = 81 (compensation-we take one away to give it to the other one)

49 - 32 = if we give to one, we give to both.

50 - 33 = (hundred chart strategy to solve)

50 - 30 = 20

20 - 3 = 17

51 - 32 =

50 - 32 =

50 - 30 = 20

20 - 2 = 18

18 + 1 = 19 (because we still had 1 from the 51)

or

50 - 31 = (I take away 1 from both right away)

50 - 30 = 20

20 - 1 = 19

Place value

Fraction takes a HUGE portion of the time in 3rd grade. I like to give my students and my 3rd grade colleague a head-up about them.

When we go back to school, we will spend a lot of time on this.

Goals:

• understanding that a fraction is an EQUAL part of a whole.
• writing a fraction, 'reading' a fraction (being able to say it)
• 2nd grade goal (but I usually push them further:) is to just have them understand what 1/2, 1/3, 1/4 is.

The language I use is to say about 1/3 for example: we cut it in 3 equal parts and I take one...ALWAYS start with the denominator (bottom number) please.
