Aktiwiteit: tessellasies [lo 1.8]

24. TESSELLASIES

24.1 Het jy geweet?

Wanneer jy ’n vlak met teëls bedek sonder dat daar openinge tussen die teëls gelaat word, word die patroon ’n tesselasie genoem, bv.

Ons sê die vorm tesseleer .

24.2 Dink jy ALLE veelhoeke sal tesseleer? __________ Motiveer jou antwoord.

24.3 Gebruik ’n kombinasie van veelhoeke, bv. ’n driehoek en ’n vierkant, en ontwerp ’n tapyt vir ’n kombuis / badkamer. Dit moet teselleer! Kleur dit netjies in.

25. Tyd vir selfassessering

  • Kleur die gesiggie in wat waar is van jou:
Ek kon verskillende driehoeke op grond van hul eienskappe groepeer
Ek kan die volgende begrippe verduidelik:
  • skerphoekige driehoek
  • gelykbenige driehoek
  • stomphoekige driehoek
  • gelyksydige driehoek
  • reghoekige driehoek
  • ongelyksydige driehoek
  • simmetrie
  • tessellasie
Ek kan simmetrie-asse van figure aandui
Ek kan ’n figuur teken wat tesseleer

26. Kan jy die punt van jou vorige hoofrekentoets verbeter? Probeer dié een binne 2 minute voltooi.

a) 16 + 19 + 15 = ____________

b) 28 + 36 + 41 = ____________

c) 1 009 – 16 = ____________

d) 1 012 – 17 = ____________

e) ____________ x 8 = 96

f) 9 x ____________ = 108

g) 84 ÷ 7 = ____________

h) 63 ÷ ____________= 9

i) 10 5 ÷ 103 = ____________

j) 10³ x 102 = ____________

k) 43 ÷ 8 = ____________

l) 59 ÷ 6 = ____________

m) 78 ÷ 9 = ____________

n) 86 ÷ 9 = ____________

o) 53 ÷ 7 = ____________

27. UITDAGING!

  • Kyk of jy die volgende kan regkry:

27.1 Rangskik 20 tandestokkies om sewe vierkante te vorm (sien skets). Skuif drie vuurhoutjies sodat slegs vyf vierkante van dieselfde grootte oorbly.

27.2 Pak jou tandestokkies soos in die voorbeeld hieronder. Skuif slegs twee sodat jy ’n parallelogram en drie ruite vorm.

27.3 Trek die volgende stukke van ’n tangram oor op folio en knip dit netjies uit (of gebruik ’n tangram as julle een in die klas het).Gebruik al die stukke en bou ’n kat op soveel verskillende maniere as wat jy kan.

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder hoofberekeninge doen wat kwadrate van natuurlike getalle tot minstens 10 2 en derdemagswaardes van natuurlike getalle tot minstens 5 3 behels.

what are pathogens
Don Reply
In biology, a pathogen (Greek: πάθος pathos "suffering", "passion" and -γενής -genēs "producer of") in the oldest and broadest sense, is anything that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term pathogen came into use in the 1880s.[1][2
